Abstract
Provided is a semiconductor device that suppresses the occurrence of defects due to photocorrosion. A method for manufacturing the semiconductor device includes the steps of: forming an insulating layer with a concave portion over a substrate; forming a conductive film over the insulating film and the inside of the concave portion; polishing and removing the conductive film positioned over the insulating layer; and cleaning the insulating layer in a light-shielded state. Between the step of polishing and the step of cleaning, or after the step of cleaning, the substrate SUB is moved by detecting the presence or absence of the substrate SUB in the light-shielded state using an infrared sensor.
