Abstract
The present invention provides a method of manufacturing a fin field effect transistor, comprising: providing an SOI substrate comprising a substrate layer (100), a BOX layer (120) and an SOI layer (130); forming a basic fin structure from an SOI layer; forming source/drain regions (110) on both sides of the basic fin structure; forming a fin structure between the source/drain regions (110) from a basic fin structure; and forming a gate stack across the fin structure. The method of manufacturing a fin field effect transistor provided in the present invention can integrate a high-k gate dielectric layer, a metal gate, and stressed source/drain regions into the fin field effect transistor to enhance the performance of the semiconductor device.
