Skywater Technology Inc
A U.S.-based pure-play semiconductor foundry, SkyWater makes chips that other companies design, running wafer factories in Minnesota and Austin that serve aerospace, defense, and quantum-computing customers. It was founded in 2017 when the firm Oxbow Industries bought a Minnesota fab from Cypress Semiconductor, a facility tracing back to a 1991 spinoff from Control Data. SkyWater has also helped fabricate qubits for quantum computers, and in 2026 agreed to be acquired by the quantum firm IonQ.
