Abstract:
A method for fabricating a layer structure in a trench includes: simultaneously forming a dielectric film containing a Si—N bond on an upper surface, and a bottom surface and sidewalls of the trench, wherein a top/bottom portion of the film formed on the upper surface and the bottom surface and a sidewall portion of the film formed on the sidewalls are given different chemical resistance properties by bombardment of a plasma excited by applying voltage between two electrodes between which the substrate is place in parallel to the two electrodes; and substantially removing the sidewall portion of the film by wet etching which removes the sidewall portion of the film more predominantly than the top/bottom portion according to the different chemical resistance properties.

Claim (Index 3):
The method according to  claim 1 , wherein in step (i), a halogenated silane is used as a precursor.
