摘要： Forming of a first silicon oxide film is started on an internal surface of a trench formed on a surface or upwardly of a semiconductor substrate according to an HDP technique. Then, deposition of the first silicon oxide film stops before an opening of the trench closes. Further, the first silicon oxide film deposited in the vicinity of an opening is etched, and a second silicon oxide film is formed on the first silicon oxide film deposited on the bottom of the trench according to the HDP technique. In this manner, the first and second silicon oxide films can be laminated on the bottom of the trench.

摘要： According to one embodiment, a stacked film including at least a silicon oxide film is formed by stacking a plurality of films formed of different materials and a hard mask pattern is formed on the stacked film. Then, a stacked film pattern of a predetermined shape is formed by performing anisotropic etching on the stacked film by using the hard mask pattern as an etching mask and the hard mask pattern is removed. The hard mask pattern is formed by stacking at least one first hard mask layer and at least one second hard mask layer. The first hard mask layer is formed of a material having a higher removability in wet etching than the second hard mask layer. The first hard mask layer is arranged immediately above the stacked film.
