Complementary FETs with wrap around contacts and methods of forming same
Abstract:
The present disclosure relates generally to wrap around contact formation in source/drain regions of a semiconductor device such as an integrated circuit (IC), and more particularly, to stacked IC structures containing complementary FETs (CFETs) having wrap around contacts and methods of forming the same. Disclosed is a stacked IC structure including a first FET on a substrate, a second FET vertically stacked above the first FET, a dielectric layer above the second FET, and a spacer layer between FETs, wherein each FET has an electrically isolated wrap-around contact formed therearound.
