Abstract

A method for forming a deposition film by introducing a starting gas for formation of a deposition film into a reaction chamber housing a substrate therein and forming a deposition film on the substrate by irradiation with light comprises performing deposition by using a monochromatic light and a continuous polychromatic light in combination and projecting the lights on the substrate on which the deposition film is to be formed.
