Abstract:
1. A substrate cleaning apparatus for cleaning a substrate having an end surface, a front peripheral portion and a rear peripheral portion, the substrate cleaning apparatus comprising: a substrate holding mechanism configured to rotatably hold a substrate; a substrate rotating mechanism configured to rotate the substrate held by the substrate holding mechanism; a cleaning-liquid supply mechanism configured to supply a cleaning liquid to the substrate held by the substrate holding mechanism; a cleaning mechanism including a brush made of a sponge-like resin, which is brought into contact with at least an end surface of the substrate during the cleaning, and a brush compressing mechanism configured to compress the brush; a horizontally moving part configured to horizontally move the cleaning mechanism; and a vertically moving part configured to vertically move the cleaning mechanism, wherein the brush is made to be in contact with and to clean at least the end surface of the substrate by the horizontally moving part and the vertically moving part, under a state in which the brush is compressed and hardened by the brush compressing mechanism and the brush compressing mechanism is independent or the horizontally moving part and the vertically moving part.
