about IIM

History of Rapidus

Rapidus Corporation was established in August 2022 to create advanced semiconductor and packaging technologies. Our mission is to improve efficiency, reduce power and improve the ecological impact of advanced computing in datacenters, autonomous vehicles, industrial manufacturing and artificial intelligence.
