Device with MOSFET on SOI

摘要

The device (1) has an upper region (102) including a MOSFET type semiconductor device i.e. P-channel MOS transistor (106), with a metallic gate (108) and arranged on a semiconductor layer (118). A lower region (104) has a MOSFET type semiconductor device i.e. N-channel MOS transistor (134), arranged on a portion (132b) of another semiconductor layer, where the layers are made of strained silicon. The transistor (134) has a gate (128b) formed by a portion of a metallic layer. The latter semiconductor layer is arranged on an insulating layer (146) stacked on another metallic layer (148). An independent claim is also included for a method of manufacturing a silicon-on-insulator MOSFET device.
