Spark’s back on Indian electronics!!


Well, well, well! Post the announcements by the Government of India last week of two 300mm fabs in India, there have been a spate of announcements again, this week! Here’s what they are!

Yesterday evening, the Indian Cabinet Committee on Economic Affairs has approved setting up of Information Technology Investment Region (ITIR) near Hyderabad.

The Phase I of this project will be from 2013 to 2018 and Phase II will be from 2018 to 2038. The Government of Andhra Pradesh has delineated an area of 202 sq. kms. for the proposed ITIR in three clusters/ agglomerations viz.:

(i) Cyberabad Development Area and its surroundings,
(ii) Hyderabad Airport Development area and Maheshwaram in the south of Hyderabad, and
(iii) Uppal and Pocharam areas in eastern Hyderabad. The ITIR will be implemented in two phases.

Next, the Government of India finalized the setting up of a ‘Ultra-Mega Green Solar Power Project’ in Rajasthan in the SSL (Sambhar Salts Ltd, a subsidiary of Hindustan Salts Ltd – a Central Public Sector Enterprise under the Department of Heavy Industry, Ministry of Heavy Industries & Public Enterprises) area close to Sambhar Lake, about 75 kms from Jaipur.

Further, India was recognized as ‘Authorizing Nation’ under the international Common Criteria Recognition Arrangement (CCRA) to test and certify electronics and IT products with respect to cyber security. India has become the 17th nation to earn this recognition.

Then again, the ‘HTML 5.0 Tour in India’ has now reached Hyderabad.

Also, India has offered to help Cuba develop its renewable energy resources. This has been conveyed to Marino Murillo, vice president of the Republic of Cuba at Havana, by Dr. Farooq Abdullah, Minister of New and Renewable Energy, during his trip to Cuba.

All of this is really brilliant stuff!

At least, I have never seen or heard about so much activity happening, especially in the electronics and solar PV sectors. One sincerely hopes that all of these initiatives will allow India to come to the forefront of the global electronics industry.

The spark seems to be coming back to the India electronics industry, after a very, very long wait! It is hoped that this stays on!!

300mm is the new 200mm!


300mm fabs.

Buyers of 300mm fabs.

300mm is the new 200mm, said GlobalFoundries’ David Duke, during a presentation titled ‘Used Equipment Market’ at the recently held Semicon West 2013 in San Francisco, USA. Used semiconductor equipment sourcing and sales is a very interesting challenge.

Qimonda, Spansion, Powerchip and ProMOS had jumpstarted the market. Now, there is a broadening user base. There is an unexpected uptake by analog and power device producers to achieve economies of scale. There has been legacy logic scaling. Also, the 200mm fabs are being upgraded to 300mm with used equipment. Many 300mm tools can “bridge” to 200mm easily.

Parts tools are seeding the ecosystem. Third parties are also able to support refurb as well as tool moves. However, we need more! Software licensing is becoming a smaller hurdle. There has been no over-supply yet!

So, what are the ‘rough’ rules of thumb for 300mm? First, there are approximately 1,500 individual tools in the open market. Few sellers know the values as the market is still developing. Twenty percent of the transactions drive 80 percent of sales. Today, the number of 300mm buyers is around  1/10th the number of 200mm buyers!

Lithography has been the biggest difference. Leading edge DRAM is far more expensive in lithography. Lithography has seen the most dramatic financial effects with explosive pricing in technology (immersion) and the need for capacity (two-three critical passes vs. one with dual/triple gate patterning. As of now, financial shocks and bankruptcies are the main drivers for used 300mm.

Next, 200mm is now the new 150mm! The 200mm OEM support is starting to dry up. It is nearly impossible to compete in productivity vs. 300mm. Oversupply is causing values to stay suppressed. The only bright spot being: there is still strong demand for complete fabs. The 200mm market split is roughly by 40 percent Asia and 60 percent rest of the world.

So, what are the likely alternative markets for 200mm and 300mm fabs? These are said to be MEMs and TSV, LEDs and solar PV.

That brings me to India! What are they doing about fabs over here? This article has enough pointers as to what should be done. Otherwise, the world is already moving to 450mm fabs! Am I right?

Convergence of PV materials, test and reliability: What really matters?


SEMI, USA recently hosted the seminar on ‘Convergence of PV Materials, Test and Reliability: What Really Matters?

Reliability in growing PV industry
Speaking on the importance of reliability to a growing PV industry, Sarah Kurtz, principal scientist, Reliability group manager, NREL, said that confidence in long-term performance is a necessity in the PV industry. Current failure rates are low. There is need to demonstrate confidence so that failure rates will stay low. There has been exponential growth of the PV industry so far. PV is a significant fraction of new installations. It now represents a significant fraction of new electricity generating installations of all kinds.

How does one predict the lifetime of PV modules? There has been a qualification test evolution for JPL block buys. Most studies of c-Si modules show module failures are small. Internal electrical current issues often dominate.

The vast majority of installations show very low PV module failure rates (often less than 0.1 percent). There has been evidence that PV is low risk compared to other investments. To sustain the current installation rate, we need to demonstrate confidence that justifies the annual investment of $100 million or so.

Critical factors in economic viability of PV
DuPont has broad capabilities under one roof. It offers materials, solar cell design, and processes integrated with panel engineering. Speaking about Critical factors in economic viability of PV – materials matter – Conrad Burke, global marketing director, DuPont PV Solutions, said that material suppliers have a distinct advantage to view trends. The industry can expect consolidation among large PV module producers and large materials suppliers.

There is an increasing dependence on materials suppliers for processes, tech support and roadmap. There is renewed attention to long-term reliability and quality of materials in PV products.

There is a race for survival among panel producers. There are dropping prices for solar panels, and quality is getting compromised. There are reduced incentives in established markets. The market will continue to grow. Key factors that determine investment return for PV include lifetime, efficiency and cost.

When materials fail, the consequences are dire. There are failures such as encapsulant discoloration, backsheet failure, glass delamination, etc. Average defect rates in new-build modules has been increasing. Significant number of PV installations do not deliver the projected RoI. The system lifetime is as important as cost and incentives.

Solar cell power continues to improve. There have been improvements from metal pastes and processes. Performance loss impacts the RoI. The US Department of Energy hired JPL to develop 30-year PV modules. Recent cost pressures have led to the dramatic changes in module materials and a lack of transparency.

Analyzing modules from the recent service environments show performance issues. Certification does not mitigate risk. Tests do not predict the actual field performance. He showed tier-1 solar panel manufacturing problems from China, Japan and the USA. Backsheet is critical to protect solar panels. Few materials have lengthy field experience. We will continue to see drop in prices for solar panels and opening of new markets. Focus for PV module makers will remain efficiency, etc.

Five-year outlook for solar PV industry!


According to Finlay Coville, VP and team leader, NPD Solarbuzz, full year end market PV demand during 2012 reached 29.05 GW. The demand is forecast to increase to 31 GW in 2013. China is expected to replace Germany as the leading market for the first time. The global market is likely to have a CAGR exceeding 15 percent, highlighting long term confidence in global PV adoption levels.

Supply vs. demand overview in 2012
The upstream c-Si module/thin-film panel suppliers produced 30.1 GW of new product in 2012. Combined with inventory levels through the value chain, this provided 31 GW of panels to the downstream channels. 29 GW was used for market demand, while 2 GW went to the downstream inventory.

Demand overview 2013
Year 2013 is shaping up as a 31 GW demand year under the most likely scenario. Over 50 percent of the end market demand is projected to come from China, Germany and North America (USA and Canada). 2013 will be a transition year for the emerging PV territories. Both the Middle East and Africa and Emerging Asia will likely reach 1 GW.

Source: NPD Solarbuzz, USA.

PV demand in 2012 accounted for approximately 30 percent of all PV installed globally. The industry growth in 2012 is positive, but set against a backdrop of an industry that had been accustomed to year-on-year growth often exceeding 100 percent. The industry is forecast to return to double digit growth.

PV scenario forecasting continies to show divergent outcomes in 2017. A high market demand scenario assumes a strong economic environment and aggressive PV policies by way of direct incentives and lower regulatory hurdles.

Five-year cumulative demand by geography
Cumulatively, global PV demand is forecast to exceed 230 GW over the five year period to 2017. China is forecast to install 51 GW accounting for over 20 percent. Europe will continue to offer strong regional PV market. North America and Japan will provide over 61 GW of demand. Emerging markets are projected to create over 25 GW of PV demand, more than 10 percent of the cumulative total to 2017.

By application segment, the ground-mount segment will remain the single largest segment over the five years. Residential and non-residential (commercial) segments will continue to be characterized by specific end-user requirements, different supply channels and routes-to-market for upstream suppliers.

The PV industry was configured to supply over 45 GW in 2012. The industry is likely to be in an over-capacity mode in 2013, with balanced supply/demand levels restored from 2015. Market share aspirations remain a key driver for PV manufacturers. During 2013 and 2014, the capacity taken offline is likely to be more than compensated for by newly ramped capacity.

With multi-domain c-Si module production, most panels had efficiencies in the 13-16 percent band during 2012. High efficiency concepts are not likely to strongly influence the module efficiency landscape during 2013 or 2014. If high efficiency cell types gain traction, the share of modules with efficiencies above 16 percent will increase.

In 2012, a wide range of efficiencies were produced, but with levels that do not compete with c-Si modules for space-constrained applications. The range of panels available in the 12-14 percent band is likely to grow strongly from 2015 as leading suppliers benefit from process improvements. Panels below 10 percent efficiency will become obsolete.

Despite end market growth expected, revenues available to each part of the value-chain will see strong declines Y/Y in 2013. This is due to the ASPs declining at a faster rate than the end-market demand growth, within a strong overcapacity environment. Revenues are also unlikely to recover for each value-chain segment until the 2016-2017 period.

What’s with prices?
2012 was the fourth year in a row that c-Si module prices declined and was the largest Y/Y decline. As capacity throughout the PV chain has increased, the oversupply has put further pressure on the ASPs. Declines in pricing occurred further upstream, at the poly, wafer and cell segments.

Tracking SAM revenues fron selling modules into downstream channels is becoming less important to the PV industry. as a number of module suppliers take on EPC and project developer roles.

PV equipment spending
As for PV equipment spending, the most likely forecast sees capacity being added by a select gtoup of tier 1 c-Si makers during 2014. The next cyclic downturn is forecast for 2016-2017. This assumes excess capacity is added in the next upturn.

If we look at the current scope of trade disputes, there are five major markets — EU, USA, India, Canada, China — investigating products being imported, with China featuring in most cases. Most disputes are being pursued by the internal bodies, but several have been referred to the WTO for review. A growing number of emerging PV regions already have domestic content incentives.

Summary
PV demand was 29 GW in 2012, and 2013 is forecast to tip 31 GW. 230 GW of new PV demand is forecast between 2013-2017, adding to the 100 GW at the end of 2012. Eighty percent of PV demand in 2013-2017 will come from the top 10 end markets.

Obama urges US to ‘keep going’ in clean energy!

February 13, 2013 4 comments

US president Barack Obama.

US president Barack Obama.

I was watching US president Barack Obama deliver the state of the union address. There was lot of positiveness. First, he urged the Congress to get together and pursue a bipartisan, market-based solution to climate change. He called for the nation to embrace the need for modest reforms in medical healthcare.

The USA’s first priority is making America a magnet for new jobs and manufacturing. After shedding jobs for more than 10 years, the US manufacturers have added about 500,000 jobs over the past three years. Caterpillar is bringing jobs back from Japan. Ford is bringing jobs back from Mexico. And this year, Apple will start making Macs in America again. That should great news for the Americans!

Following the first manufacturing innovation institute in Youngstown, Ohio, Obama announced the launch of three more manufacturing hubs, where businesses will partner with the Department of Defense and Energy to turn regions into global centers of high-tech jobs. He asked the Congress to help create a network of 15 hubs and guarantee that the next revolution in manufacturing is made in America.

America, he said, was poised to control its energy future. The US has doubled the amount of renewable energy generated from sources like wind and solar — with tens of thousands of good American jobs to show for it. He urged the Congress to pursue a bipartisan, market-based solution to climate change.

Four years ago, other countries dominated the clean energy market and the jobs. Last year, wind energy added nearly half of all new power capacity in America. He called to generate even more. Solar energy gets cheaper by the year — there’s a need to drive down costs even further! He urged the US to keep going all in on clean energy, like China. Obama added that those states with the best ideas to create jobs and lower energy bills by constructing more efficient buildings will receive federal support to help make that happen.

The initiatives in manufacturing, energy, infrastructure, housing — will help entrepreneurs and small business owners expand and create new jobs. However, none of it will matter unless the US equips citizens with the skills and training to fill those jobs. That has to start as early as possible, he urged!

Obama has signed a new executive order that will strengthen USA’s cyber defenses by increasing information sharing, and developing standards to protect national security, jobs, and privacy. He called upon the Congress to pass legislation that would give the government a greater capacity to secure USA’s networks and deter attacks.

As Obama said during his speech, “The greatest nation on Earth cannot keep conducting its business by drifting from one manufactured crisis to the next!” Can India, at least, learn?

10 key trends for global PV industry

February 11, 2013 1 comment

Finlay Colville, vice president, NPD Solarbuzz, USA, recently presented the 10 key trends for the PV industry. According to him, the 10 key trends are:

1. PV demand growth. The industry has been characterized by strong growth rates of 25 percent to >100 percent Y/Y for the past decade. Now, the industry needs to plan for growth at more modest levels.

2. Globalization of PV demand. The emerging regions emerged for PV demand in 2012.

3. China end-market demand in 2013. China is forecast to account for approximately 25 percent global demand in 2013. The emerging demand is confined to a select group of countries across the three emerging regions.

4. Capacity imbalance reset. The nameplate capacity levels at the 60-GW level are often cited. However, the the PV industry currently has an ‘effective’ capacity of 41-42 GW. Therefore, demand needs to exceed 40 GW for proper reset.

Top module suppliers.

Top module suppliers.

5. Competitive shakeout. The top-10 module suppliers by MW for 2012 only comprised 50 percent of the year shipments. Also, a similar pattern is seen for c-Si cell production. We can expect another two years of shakeout on the supply side.

6. Cost and price rationalization. Every segment of the supply side is subject to price/cost pressure: from poly to BoS supply. Even reducing the silicon/nonsilicon costs of modules to 53c/W level by the end of 2013 may still result in negative gross margins.

7. Supply and demand rationalization. The poly suppliers have been operating at reduced utilization since 2H’12.

8. Evolution of PV technology roadmaps. Strong marketshare gains from standard c-Si multi ingot/wafers. The end-markets are driving module efficiencies and power ratings. The alternative growth methods have not gained traction and are being phased out.

9. Capital expenditure cyclic patterns. The PV process equipment suppliers have been impacted severely by overcapacity and overinvestments of 2010 and 2011. There is a strong chance that 2014 will end up as low as 2013. Also, technology-buy cycles don’t exist as yet in the PV industry.

10. Domestic protectionism counter measures. The effects of trade wars may yet have a profound effect on the PV industry into 2014. There will be direct effect of global overinvestment into domestic manufacturing. The other countries have an impact, but China and Europe decisions are key.

In summary, the PV industry is a 30-GW end-market today, and is forecast to grow to the 40-GW level in 2015. Europe demand is declining, but greater number of countries/territories expected to provide new PV demand. Demand in China during 2013 is essential for local suppliers.

The PV industry is capable of producing 12-15 GW per quarter. Supply and demand need a 40-GW+ market to balance. The shakeout phase is proceeding slowly, and will continue for the next two years. Reducing costs are not yet keeping up with price declines. ASP and ISP stabilization period is needed badly.

The end-market demand has become dependent on low ISPs. Also, multi c-Si based modules are dominating the industry. PV equipment suppliers are unlikely to see meaningful new order intake until 2014 or beyond. Finally, trade wars and domestic protectionism measures are crucially dependent on the EU and China decisions in 2013.

Opportunities in turbulent PV equipment market

December 19, 2012 1 comment

Ms. Fatima Toor, analyst, Lux Research, recently presented on opportunities in turbulent PV equipment market, in association with SEMI, USA.

Global PV market trends
Bankruptcies are galore. Eg. Solyndra, Abound Solar, Konarka, etc. Global trade wars are also on the rise. There are US tariffs on Chinese solar cells. There is also an EU investigation on Chinese solar panels. Then, there are Chinese investigations on US, EU and Korean polysilicon dumping. Government incentives have been lowered in the EU, but raised in Asia and Americas. Following Barack Obama’s re-election in the US, the environmentalists are again upbeat about green energy.

Crystalline Si remains dominant.

Crystalline Si remains dominant.

Global PV demand increase will be driven by Asia and Americas in the coming years. Emerging markets will grow over six times in size from 2011-2017. Crystalline Si will be the dominant installed PV technology, at least till 2017. Gap between demand and supply will close.

The Q3-12 geographical capacity distribution would be across PV value chain. China leads in polysilicon, cells and modules supply. Chinese equipment manufacturers market share has been on the rise, ramping up competition for Western equipment suppliers.

Lux Research sampled 493 PV manufacturers. Of these, 40 percent are based in the EU, 28 percent are based in China, 17 percent are in the US and 15 percent are in the Rest of the World.

Opportunities for equipment manufacturers in current market state
Cost, efficiency and price are fundamental drivers of PV industry. Innovations across the value chain will enable higher margins for PV industry. The desire for cell and module manufacturers to reduce costs and differentiate will drive opportunities for equipment manufacturers.

Crystalline Si technology: Innovations across crystalline Si value chain would enable opportunities for equipment suppliers. Fluidized bed reactor (FBR) process requires 10 lWh/kg and is a continuous process. Why is FBR only 6 percent of total polysilicon capacity today? The reasons are:
* No off-the-shelf FBR reactors are available.
* Process complexity requires that Si granules can be polluted by impurities.
* There is an opportunity for equipment manufacturers to develop off-the-shelf FBR equipment that will enable reduced production costs for polysilicon.
* GCL announced developing its FBR technology.
* Samsung Fine Chemicals and MEMC have partnered to set up FBR polysilicon production due to its lower production costs.

Monocrystalline silicon (c-Si) ingot growth using Czochralski (CZ) method is high cost and results in pseudo-square c-Si wafers. Plate seed for qc-Si ingot growth with mc-Si grains on the edges and c-Si in the middle. ReneSola has technology with wafer capacity of 2GW of which 1.6GW is qc-Si Virtus wafers and 0.4GW are c-Si wafers. ReneSola is likely to be one of the Chinese companies to survive the shakeout due to its strategy and technology.

Opportunities exist to optimize qc-Si ingot growth. Modified directional solidification (DS) furnace makers claim 90 percent c-Si and 10 percent mc-Si yields during qc-Si ingot growth. In reality, 60 percent c-Si and 40 percent mc-Si results in high wafer binning and sorting costs. This provides an opp for equipment manufacturers to improve the c-Si yield to higher than 90 percent. The Qc-Si capacity is likely to increase in the coming years as DS furnace manufacturers innovate.
