Abstract:
1. A substrate processing apparatus, comprising: a substrate holding and rotating mechanism, having a spin base arranged to rotate around an axis of rotation, for holding and rotating a substrate; at least two positioning members provided on the substrate holding and rotating mechanism for positioning the substrate at a predetermined substrate holding position, the positioning members being fixed to the spin base such that the positioning members are unmovable relative to the spin base, with a first distance between the positioning members; a substrate transfer mechanism for transferring the substrate to the substrate holding and rotating mechanism; a pressing unit disposed on the substrate transfer mechanism for pressing the substrate toward the positioning members in a pressing direction; and a control unit programmed to execute a step of pressing a substrate to the positioning members by use of the pressing unit disposed on the substrate transfer mechanism, wherein the substrate transfer mechanism includes a substrate holding hand for holding the substrate, the substrate holding hand includes a substrate contact portion provided at a base end of the substrate holding hand and arranged to come in contact with an end face of the substrate, and a pair of support members provided at a tip end of the substrate holding hand with a second distance between said support members longer than the first distance, the pressing unit includes a substrate-contact-portion moving mechanism for moving the substrate contact portion toward the positioning members, and the at least two positioning members are disposed between the pair of support members when viewed in the pressing direction.
