Future Transistor Stacking Plans Start to Diverge (opens in new tab)

IEEE VLSI Symposium in Honolulu and detailed today by IBM points toward two main paths.Though companies have different names for it, in research this future device is commonly called the CFET, for complementary field effect transistor. It takes the two types of transistor, the p-channel and n-channel field effect transistor (PFET and NFET), that make up complementary metal-oxide semiconductor (CMOS) logic and stacks them instead of placing them side by side. Specifically, it stacks a type of ...
