Claim:
1. A liquid treatment apparatus comprising: a substrate holding member that holds a substrate horizontally; a rotation mechanism that rotates the substrate holding member; a chemical liquid nozzle that supplies a chemical liquid to the substrate held by the substrate holding member; a top plate that covers the substrate held by the substrate holding member from above the substrate; a rotation driving mechanism that rotates the top plate about a vertical axis; a moving arm that moves the top plate; at least one LED lamp that heats the substrate during a chemical liquid treatment by irradiating the substrate with light of a predetermined wavelength transmitted through the top plate from above the top plate; and a lamp support supporting the LED lamp, wherein the LED lamp and the lamp support are non-rotatably fixed to the moving arm such that the LED lamp and the lamp support are separated from the top plate by a vertical gap therebetween, and wherein the LED lamp is movable so as to face different radial regions of the substrate held by the substrate holding member.
