Three dimensional CMOS integrated circuits having device layers built on different crystal oriented wafers

Three-dimensional (3D) integration schemes of fabricating a 3D integrated circuit in which the pFETs are located on an optimal crystallographic surface for that device and the nFETs are located on a optimal crystallographic surface for that type of device are provided. In accordance with a first 3D...
