STRUCTURE AND METHOD OF FABRICATING A HYBRID SUBSTRATE FOR HIGH-PERFORMANCE HYBRID-ORIENTATION SILICON-ON-INSULATOR CMOS DEVICES

摘要

The present invention provides a method of integrating semiconductor devices such that different types of devices are formed upon a specific crystal orientation of a hybrid substrate that enhances the performance of each type of device. Specifically, the present invention provides a method of integrating semiconductor devices such that pFETs are located on a (110) crystallographic plane, while nFETs are located on a (100) crystallographic plane of a planar hybrid substrate. The method of the present invention also improves the performance of creating SOI-like devices with a combination of a buried insulator and counter-doping layers. The present invention also relates to semiconductor structures that are formed utilizing the method of the present invention.
