摘要:
A method of manufacturing a semiconductor device includes measuring the reflectance at the surface of a semiconductor substrate provided with concave portions and deciding a deposition parameter that represents a deposition condition corresponding to the measured reflectance. Then, a metal film is formed on the semiconductor substrate under a condition corresponding to the deposition parameter.
