Japanese chipmaker Rapidus begins test production of 2nm circuits — company commits to single-wafer processing ahead of 2027 mass production target

Good news! Is Rapidus catching up with TSMC and Samsung? Competition is good, more competition is better.

"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. ...

Nowadays, large chipmakers like Intel, Samsung, and TSMC use a combination of batch and single-wafer processing methods in their semiconductor fabrication processes. ..."
