EV Group (EVG), a leading
supplier of wafer bonding and lithography equipment for the MEMS, nanotechnology
and semiconductor markets, today announced receipt of its first order from the
Fraunhofer Research Institution for Electronic Nano Systems ENAS (Chemnitz,
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
"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.
Those interested in learning more about EVG's SMS-NIL technology and broad
portfolio of wafer bonding and lithography equipment are invited to visit the
company in booth #1568 (Hall 1) during SEMICON Europa, October 19-21, 2010,
at Messe Dresden, Dresden, Germany.
