Abstract
There can be obtained a method for manufacturing a semiconductor device in which adherence of particles can be suppressed and printing onto a substrate can be done. The method for manufacturing a semiconductor device includes the steps of: preparing a substrate formed of a semiconductor; forming a protective film to cover at least a part of a main surface of the substrate; and doing printing onto the substrate by irradiating, with laser, the main surface having the protective film. In the step of forming a protective film, the protective film made of a material having a band gap larger than that of the semiconductor constituting the substrate is formed. In the step of doing printing onto the substrate, the substrate is irradiated with laser Lb having such a wavelength that an absorptance of the material for the protective film is smaller than that of the semiconductor constituting the substrate.
