China's 3nm-Class GAA Transistor Claim: What a 500,000 On-Off Ratio Actually Proves
China's Institute of Microelectronics reportedly built a GAA transistor path toward sub-3nm nodes without relying on EUV. But a 500,000 on-off ratio only confirms single-device performance—key questions on power, performance, area, interconnects, and yield remain unanswered.
