Claim Text:
1. A substrate processing apparatus for processing a substrate, comprising: a chamber having a chamber body and a chamber cover and forming an internal space which is sealed by closing an upper opening of said chamber body by said chamber cover; a substrate holding part disposed in said internal space of said chamber, for holding a substrate horizontally; a substrate rotating mechanism for rotating said substrate together with said substrate holding part about a central axis oriented in a vertical direction; a processing liquid discharge part for discharging a processing liquid supplied onto said substrate to the outside of said chamber, a plurality of lift pins arranged in a circumferential direction about said central axis and protruding downward from said chamber cover; and a lift pin moving mechanism for moving said plurality of lift pins in said vertical direction relative to said chamber cover, wherein said substrate rotating mechanism comprises: an annular rotor part disposed in said internal space of said chamber, to which said substrate holding part is attached; and a stator part disposed around said rotor part outside said chamber, for generating a rotating force between itself and said rotor part, wherein respective tip portions of said plurality of lift pins are moved down from an escape position to a transfer position by said lift pin moving mechanism, and said substrate is transferred between said plurality of lift pins and said substrate holding part at said transfer position.
