TSMC Implements Backside Power Delivery For GPUs
|
9.1
TSMC's A16 node introduces backside power delivery and redesigned transistors to address long-standing leakage and power-delivery limits in modern chips. The approach flips chips to route power from the back and targets roughly 30% voltage loss in microscopic copper wiring and atomic-scale leakage that create heat and inefficiency. The changes enable higher-power, cooler GPUs for AI data centers, improving energy efficiency and thermal headroom.
