| 摘要 |
The present invention relates to a field effect transistor (FET) containing a channel extending perpendicularly across at least one V-shaped trench and along the interior surfaces thereof. In one aspect, a semiconductor device is provided that includes a semiconductor substrate having first and second device regions that are isolated from each other by an isolation region. The first device region has a planar surface with a first crystalline orientation, and the second device region has at least one V-shaped trench which has interior surfaces with a second, different crystalline orientation. A first FET is located at the first device region and contains a channel extending along the planar surface of the first device region. A second, complementary FET is located at the second device region and contains a channel extending perpendicularly across the at least one V-shaped trench and along the interior surfaces thereof.
