Japanese chipmaker Rapidus begins test production of 2nm circuits — company commits to single-wafer processing ahead of 2027 mass production target
Rapidus on Friday announced that it had begun prototyping of test wafers with 2nm gate-all-around (GAA) transistor structures at its IIM-1 facility in Japan. The company confirmed that early test wafers are already attaining the expected electrical characteristics, which means that the company’s fab tools operate as planned and its process technology development is proceeding well. Test wafers flying over fab Prototyping is an important milestone in semiconductor production that is meant to verify that early test circuits made using a new technology behave reliably, efficiently, and meet performance targets....
