The present invention further provides a dual trench semiconductor structure in which pFETs are located on a (110) crystallographic plane, while nFETs are located on a (100) crystallographic plane. In accordance with the present invention, the devices of different polarity, i.e., nFETs and pFETs, are bulk-like devices. | 2012-05-03 |
