Patent ID: 8684014

Claim:
A liquid processing apparatus for a substrate, comprising: a holding unit comprising an elongate member configured to hold the substrate; a rotation motor configured to rotate the holding unit; a processing liquid channel configured to supply a processing liquid to a peripheral portion of the substrate held by the holding unit; and a shield unit including an opposed plate configured to oppose the substrate held by the holding unit, a heating unit configured to heat the substrate through the opposed plate, and a heated gas channel configured to supply heated gas to a surface of the substrate held by the holding unit, wherein, in the shield unit, the heating unit heats the peripheral portion of the substrate when heating the substrate through the opposed plate, and the heated gas channel supplies the heated gas to a position on the surface of the substrate, which is located inside of a point to which the processing liquid is supplied by the processing liquid channel and is located outside of an area of the substrate in contact with the holding part, and wherein the opposed plate has a diameter larger than a diameter of the holding unit, and an insulation member, having a diameter smaller than a diameter of the substrate and larger than the diameter of the holding unit, is arranged between the opposed plate and the substrate held by the holding unit.
