摘要: A substrate processing apparatus includes: a polishing pad that polishes a substrate; a pod that accommodates a polishing surface of the polishing pad, which is brought into contact with the substrate; an imaging unit that images the polishing surface of the polishing pad through the pod; and an image processing unit that processes image data imaged by the imaging unit to detect deterioration of the polishing pad.
