Abstract:
1. A semiconductor device comprising an integrated circuit including an N-channel transistor and a P-channel transistor, at least one of the N-channel transistor and the P-channel transistor comprising: an island-like single crystalline semiconductor layer comprising silicon formed on a silicon oxide layer on a supporting substrate, the island-like single crystalline semiconductor layer having at least a channel formation region and source and drain regions; a gate insulating film comprising a halogen-containing silicon oxide formed on the channel formation region and side surfaces of the island-like single crystalline semiconductor layer; a gate electrode comprising polysilicon formed over the channel formation region with the gate insulating film interposed therebetween; side walls formed adjacent to side surfaces of the gate electrode; and an interlayer insulating film formed over the at least one of the N-channel transistor and the P-channel transistor, wherein an upper portion of the gate electrode and upper portions of the source and drain regions comprise a metal silicide, and wherein the island-like single crystalline semiconductor layer comprises part of a single crystalline silicon substrate different from the supporting substrate.
