CEO interview: Sonderman on SkyWater's technology foundry model
SkyWater Technology Foundry Inc. is approaching the second anniversary of its formation as a "technology foundry" housed in mature facilities in Bloomington, Minnesota. We connected with company boss Tom Sonderman for an update on the development and plans for one of the industry's newest foundries.

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.
