Method of manufacturing semiconductor substrate dielectric isolating structure

A manufacturing method of this invention improves nonuniformity in film thickness of a circuit element formation region produced due to a poor flatness of a semiconductor substrate in the manufacture of a semiconductor substrate having a dielectric isolating structure. Mirror-polished surfaces of fi...
