OMG @IBM just announced its 0.7nm process node using homegrown NanoStack technology. It defines a route for transistors after GAA by using a staggered CFET design enabling 50% logic scaling, 40% SRAM scaling, and 666 million transistors per sq mm***.https://t.co/9Otmwq6X1b pic.twitter.com/UMilwye4Xm
