Abstract

The present invention realizes a hole-selective film provided with both hole selectivity and passivation characteristics. This production method for a semiconductor device is provided with a step for forming a titanium oxide film on a crystalline silicon layer by means of a thermal atomic layer deposition method, and a step for carrying out a hydrogen plasma process on the titanium oxide film.
