ABSTRACT:
Semiconductor devices and methods of manufacture thereof are disclosed. In one embodiment, a semiconductor device includes a first transistor having a first active area, and a second transistor having a second active area. A top surface of the first active area is elevated or recessed with respect to a top surface of the second active area, or a top surface of the first active area is elevated or recessed with respect to a top surface of at least portions of an isolation region proximate the first transistor.
