U. Washington Selects Altatech (Soitec) CVD System to Develop New Process Materials


Sans titre

The University of Washington’s Nanofabrication Facility (WNF) is the first North American institution to get an AltaCVD™ chemical vapor deposition (CVD) system (press release here). The AltaCVD system uses pulsed deposition technology to offer a unique combination of capabilities for developing new materials. It can perform atomic layer deposition (ALD) for exceptional 3D coverage at deposition rates matching those of more conventional CVD techniques. The system will be used by both internal and external researchers in fabricating a broad range of semiconductor-based devices including leading-edge CMOS transistors, MEMS, ICs built with the latest in through-silicon-via (TSV) technology, advanced LEDs and solar cells. Altatech is a subsidiary of Soitec (the world leader in SOI wafer manufacturing). AltaCVD systems have been used extensively in R&D and pilot production facilities throughout Europe; however, the University of Washington’s order represents the first such system to be delivered to a North American university R&D and pilot production facility.

Dr. Michael Khbeis, acting director of the WNF, said, “The AltaCVD system provides a unique capability that enables researchers to deposit conformal metal films for TSV applications as well as metal oxides and nitrides for high-k dielectrics and piezoelectric materials. The higher deposition rate enabled by pulsed CVD makes ALD films a tractable solution for scale-up paths toward high-volume manufacturing for our researchers and industrial clients. This ensures a viable pathway from academia to real economic impact in our region.”
