EVG secures UV-NIL order
EV Group wins order for UV-NIL/Hot Embossing Systems from Fraunhofer Research Institution for Electronic Nano Systems
EV Group (EVG) has announced receipt of its first order from the Fraunhofer Research Institution for Electronic Nano Systems ENAS (Chemnitz, Germany). Fraunhofer ENAS purchased an EVG6200NT automated mask aligner and an EVG540 automated wafer bonder, and will employ the flexible, multi-process EVG systems for mask lithography, ultraviolet nanoimprint lithography (UV-NIL), bond alignment, bonding and hot embossing (HE). The systems, which will enable Fraunhofer ENAS to process product wafers up to 200 mm in diameter, are slated for delivery in early November.
Fraunhofer ENAS closely cooperates with Chemnitz University of Technology's Center for Microtechnologies—running a state-of-the-art cleanroom facility. The institute works closely with major customers worldwide, focusing its industrial research on MEMS/NEMS, back-end-of-line (BEOL) micro and nano electronics processes, 3D IC integration and reliability. According to Dr. Thomas Gessner, a professor and director at Fraunhofer ENAS, a primary reason the prestigious institution selected the EVG systems is the advanced technology capabilities they afford. "NIL and hot embossing are key processes for extending our advanced R&D efforts," said Professor Gessner. "The EVG systems allow us to implement these technologies far better than competitive tools. We can now perform full-area nanoimprints, as well as optically aligned UV-NIL and HE, on larger wafers, further expanding our ability to support a broad spectrum of processes."
EVG's recently announced soft molecular scale UV-NIL, or SMS-NIL, technology patterns ultra-high-resolution features down to 12.5 nm on EVG's proven UV-NIL systems. The technology uses soft polymeric working stamps to avoid damaging costly master stamps, resulting in significantly lower processing costs compared to other nano-patterning techniques. EVG reports that SMS-NIL is already used in industrial environments for CMOS image sensors, micro-lens molding and other optical applications.
"This order from a leading research partner such as Fraunhofer ENAS underscores the value of our ongoing efforts to develop and implement new, leading-edge technologies that compliment and extend the applications for our systems," said Markus Wimplinger, EVG's corporate technology development and IP director. "Not only will our tools' flexibility allow Fraunhofer ENAS to perform multiple lithography, alignment and bonding processes on just two systems, but through close cooperation between both companies, processes such as EVG's unique SMS-NIL technology, as well as hot embossing processes, will be implemented and further advanced."
Further supporting its expertise in the MEMS arena, EVG announced another key order for the MEMS market today—Norway-based MEMS sensor producer Sensonor Technologies AS ordered an EVG Gemini for thermal imaging manufacturing. EVG also added another bonder to its arsenal, rolling out the new EVG®520L3 semi-automated, high-vacuum wafer bonding system for applications including metal bonding for 3D IC, MEMS, and CMOS compatibility.
