Abstract:
A method for manufacturing a semiconductor device includes providing a semiconductor structure having a substrate and a semiconductor fin on the substrate, forming a dummy gate structure on the semiconductor fin, forming a first dielectric layer on the semiconductor structure exposing an upper surface of the dummy gate structure, removing the dummy gate structure and a portion of the semiconductor fin below the dummy gate structure to form a trench that divides the semiconductor fin into a first portion and a second portion spaced apart from each other, and forming a second dielectric layer on the semiconductor structure filling the trench. The method provides a semiconductor device having a non-recessed trench isolation structure.

Claim (Index 10):
The method of  claim 8 , wherein forming the first recess and the second recess comprises:\n forming a patterned mask layer on the first dielectric layer covering the dummy gate and exposing an upper surface of the first initial gate and an upper surface of the second initial gate; removing the first initial gate and the second initial gate using the patterned mask layer as a mask; removing the patterned mask layer; removing the first initial gate insulator layer and the second initial gate insulator layer to form the first recess and the second recess.
