One of the most notable and highly differentiated technology being pursued at SkyWater is a carbon nanotube based FET process. This technology is being brought up at SkyWater under a program called 3DSoC and is funded by the Defense Advanced Research Project Agency (DARPA) under its Electronics Resurgence Initiative (ERI).
"The program objective includes demonstrating a monolithically integrated 3DSoC which is anticipated to deliver performance at 90nm geometries with a speed-power advantage of 50x compared with 7nm silicon-based performance. This technology could represent a completely new paradigm for computing and could also be further scaled to more advanced nodes for even greater performance benefits," said Sonderman.
Low dimensional materials – such as graphene and molybdenum-sulphide – have been under research for a number of years but their debut for the commercial stage is on the horizon, Sonderman said. He also said SkyWater is open to engagements on compound semiconductors such as silicon-germanium, silicon-carbide and gallium-nitride.
"We work in the MEMS space and we are working on image sensors using vanadium-oxide. The silicon photonics work has been going on for three-plus years but is now going into production. The facility has been doing superconducting work with D-Wave [on quantum computing] for six-plus years.
