Abstract: To achieve a cleaning module and a substrate processing apparatus that can improve the cleaning capability for a substrate with a simple structure. A cleaning module includes a first transfer mechanism 210-1, an ultrasonic cleaning tank 440, a transfer machine 420, and a second transfer mechanism 210-2. The first transfer mechanism 210-1 is for transferring a substrate WF with a surface to be polished facing downward up to a substrate grip or release position 418 on a downstream side along a transfer passage 405. The ultrasonic cleaning tank 440 is disposed at a position spaced apart from the transfer passage 405 and is for cleaning a substrate WF with the surface to be polished facing downward. The transfer machine 420 is for transferring the substrate WF between the substrate grip or release position 418 of the transfer passage 405 and the ultrasonic cleaning tank 440.

Abstract: Provided is a top ring that ensures uniformly pressing a substrate against a polishing pad. A top ring 302 for holding a substrate WF includes a base member 301 coupled to a top ring shaft 18, an elastic film 320 that is mounted to the base member 301 and forms a pressurization chamber 322 for pressurizing the substrate WF between the base member 301 and the elastic film 320, a substrate suction member 330 that includes a porous member 334 including a substrate suction surface 334a for suctioning the substrate WF and a pressure reducing portion 334b communicating with a pressure reducing unit 31. The substrate suction member 330 is held to the elastic film 320.

Abstract: A cooling apparatus for cooling a light source unit is provided. The cooling apparatus includes a cooling unit provided outside a path of light from the light source unit, and a heat pipe configured to connect a heat generating portion of the light source unit and the cooling unit. The heat pipe also serves as an electrode wire of the light source unit.
