Rolith’s rolling mask lithography cheaper, more scalable and flexible!

January 19, 2013

Rolith Inc., Pleasanton, California, USA-based nanotech disrupter, is developing advanced nanostructured coatings and devices based on a proprietary technology for high throughput, large surface area nanolithography.

Found in nature (moth eye, lotus leaf and others) and successfully replicated in research labs, these nanostructures have the ability to revolutionize architecture, lighting, consumer electronics, energy, data storage, life science, solar, and other industries. Rolith’s disruptive nanostructuring technology allows cost-effective scaling of nanostructures fabrication in conveyor and roll-to-roll modes.

Rolith, along with Asahi Glass Co. have recently partnered for anti-reflective glass.

Speaking about Rolith’s rolling mask lithography, Dr. Boris Kobrin, president and CEO said that essentially, Rolith has come up with a new manufacturing method based on large area low cost optical lithography, usually used in semiconductor processing (processors, memory) in a silicon wafer form factor.

“Our process is much cheaper, more scalable and flexible, applicable for much larger substrates (architectural windows, solar panels, TV displays, etc.), but at the same time, reaching and even extending resolution (smallest feature sizes) of a traditional (and high cost) optical lithography.”

How will this be better than other available solutions, especially those used in museums, galleries, etc?

According to Dr. Kobrin, currently, the used anti-reflective coatings are based on vacuum process (sputtering or ‘physical vapor deposition’ of solid metal oxide layers), pretty expensive process. Such sputtered layers add color to glass plates, have limited efficiency for wide range of colors (wavelengths) and for different angle of view.

“Our sub-wavelength (nanostructured) anti-reflective glass won’t have additional materials (just glass), will have good efficiency for an entire visible spectrum and for angles of view up to 60 deg. Moreover, due to conveyor type of manufacturing process and scalable width of such conveyor, the process promises to be quite inexpensive (we have a goal eventually to get down to $2/m2).”

How is Rolith reducing or eliminating glare from passing through the lens? “We use the technique, which nature created for some insects (moth, for example), where nanostructured surfaces eliminate reflections and make objects invisible,” he concluded.

    You’re so interesting! I do not think I’ve truly read through something like that before. So great to find somebody with a few original thoughts on this subject matter. Really.. many thanks for starting this up. This website is one thing that is needed on the internet, someone with a little originality!
