First demonstration of a CMOS over CMOS 3D VLSI Cool Cube™ integration on 300mm wafers

Abstract

For the first time, a full 3D CMOS over CMOS CoolCubeTM integration is demonstrated with a top level compatible with state of the art high performance FDSOI (Fully-Depleted Silicon On Insulator) process requirements such as High-k/metal gate or raised source and drain. Functional 3D inverters with either PMOS or NMOS on the top level are highlighted. Furthermore, Si layer transfer above a 28nm W Metal 1 level of an industrial short loop and the return in a front end environment is presented, confirming the industrial compatibility of CoolCubeTM integration.
