EVG collaborating with Eulitha on low-cost nanopatterning for HB-LEDs

EV Group (EVG) of St Florian, Austria, a supplier of wafer bonding and lithography equipment for the MEMS (micro-electro-mechanical system), nanotechnology and semiconductor markets, has signed a joint-development and licensing agreement with Eulitha AG (a spin-off of the Paul Scherrer Institute in Villigen, Switzerland that produces nanostructures using lithography techniques).

Eulitha’s PHABLE mask-based ultraviolet (UV) photolithography technology will be integrated with EVG’s automated mask aligner product platform, with the goal of developing a low-cost-of-ownership (CoO) nanopatterning solution to enable the production of high-brightness light-emitting diodes (HB-LEDs). With demonstration capabilities in place already, the first products are expected to ship later this year.

According to LED market research firm Strategies Unlimited, the market for high-brightness LEDs is expected to grow from $11.2bn in 2010 to $16.2bn in 2014, driven by applications such as TV backlighting, mobile devices and increasingly by lighting. To meet this increased demand, LED manufacturers need new manufacturing solutions that can increase the lighting efficiency of their products while keeping manufacturing costs down. Through their joint-development agreement, EV Group and Eulitha aim to explore new manufacturing technologies that support LED manufacturers’ cost and technology requirements.

Combining Eulitha’s full-field exposure technology with EVG’s mask alignment platform provides low-cost, automated fabrication of photonic nanostructures over large areas, and supports the production of energy-efficient LEDs, solar cells and liquid-crystal displays, say the firms. It combines the low cost, ease-of-use and non-contact capabilities of proximity lithography with sub-micron resolution, making it suitable for use in patterning sapphire substrates in order to enhance the light extraction (and hence efficiency) of LEDs. EVG plans to offer a PHABLE-enabled EVG620 system as an extension to its existing mask alignment system platform, giving a wider choice of configuration options.

“We look forward to working with EV Group to greatly accelerate commercialization of PHABLE through the integration of this novel technology with EVG’s industry-leading mask aligner platform,” says Eulitha’s CEO Harun Solak. “The synergies of our respective technologies have great potential to provide the resolution and volume-production capabilities of lithography steppers at a fraction of the cost, enabling LED, optics and photonics manufacturers with extremely tight cost constraints the opportunity to extend their technology roadmaps to higher levels of performance,” he adds.

“Eulitha's expertise in nanofabrication makes them an ideal partner to collaborate with on new patterning solutions for the LED industry,” comments Hermann Waltl, EVG’s executive sales and customer support director.
