发明名称 Methods of fabricating semiconductor device having shallow trench isolation (STI)
摘要 Methods of fabricating a semiconductor device include forming a field trench in a silicon substrate, forming a first oxide layer in the field trench, forming a first thinned oxide layer by partially removing a surface of the first oxide layer, and forming a first nitride layer on the first thinned oxide layer.

主权项 1. A method of fabricating a semiconductor device, comprising: forming a field trench in a silicon substrate; forming a first oxide layer in the field trench, the first oxide layer being on an inner wall and a bottom of the field trench; forming a first thinned oxide layer by partially removing a surface of the first oxide layer, the first thinned oxide layer being disposed on the inner wall and the bottom of the field trench; and forming a first nitride layer on the first thinned oxide layer to fill in the field trench.
