US Department of Defense Awards SkyWater a $27M Option to Facilitate American-Made Semiconductors Critical to National Security and Domestic Supply Chains

Government funding enables SkyWater to further develop IP for its 90 nm rad-hard FDSOI platform to be used in strategic defense and space applications

BLOOMINGTON, Minn. – July 12, 2022 – SkyWater Technology (NASDAQ: SKYT), the trusted technology realization partner, today announced the Department of Defense (DOD) is funding a $27 million Other Transactional (OT) Agreement Option to further develop intellectual property (IP) for its 90 nm Strategic Rad-Hard by Process (RH90) FDSOI technology platform. This is the latest agreement between SkyWater and the DOD to ensure a reliable and trusted source of U.S.-made chips for use in strategic defense and space applications.

This is another step in SkyWater’s RH90 technology roadmap and is part of the previously announced up to $170M investment in SkyWater by the DOD to broaden onshore production capabilities for strategic rad-hard electronics. The DOD recently determined that SkyWater has successfully completed the base prototype project.

SkyWater’s RH90 platform is based on MIT Lincoln Laboratory’s 90 nm fully depleted silicon-on-insulator (FDSOI) complementary metal-oxide-semiconductor (CMOS) process, which was engineered to produce radiation-hardened (rad-hard) electronics which can withstand harsh radiation environments. Radiation effects can rapidly degrade microelectronics, and unmitigated can cause compromised performance, malfunctions or complete failure. Lincoln Laboratory developed the FDSOI process for making integrated circuits resistant to degradation and malfunction caused by extreme radiation levels.

“As the only U.S.-investor owned and operated pure-play semiconductor foundry, we are committed to our role in reshoring chip manufacturing. This collaboration with the DOD is one example of SkyWater’s many public-private partnerships that enable great strides toward further securing and strengthening our domestic semiconductor supply chains,” said SkyWater President and CEO Thomas Sonderman. “As the U.S. continues to lead the world in technology innovation, SkyWater will continue striving to meet the critical needs of the U.S. government by providing the Trusted semiconductor technology required to domestically manufacture devices for defense and aerospace applications.”
