Abstract:
A method of manufacturing an optical semiconductor device includes preparing a semiconductor substrate having a plurality of photoelectric conversion parts, forming a trench in the semiconductor substrate to separate the plurality of photoelectric conversion parts from each other, forming a boron layer on an inner surface of the trench by a vapor phase growth method, and forming an accumulation layer in the semiconductor substrate along the inner surface of the trench by performing a thermal diffusion treatment on the boron layer.
