Abstract:
A semiconductor device manufacturing method comprising the steps of:forming a trench on a surface of a semiconductor substrate;deforming said trench by a thermal treatment under reduced pressure such that, while a section of said trench when cut by a first plane perpendicular to a direction of a depth of the trench is defined as a first section and a section of said trench when cut by a second plane perpendicular to the direction of the depth of the trench and closer to a bottom of said trench than said first plane is defined as a second section, an area of said first section is smaller than an area of said second section and that a minimum radius of curvature of said first section is smaller than a minimum radius of curvature of said second section; andembedding an interior of said trench with an embedding member.
