Claim 10:
11. An apparatus for treating a substrate, the apparatus comprising:
a support plate configured to support the substrate; and
a liquid supplier configured to dispense a treatment liquid onto the substrate supported on the support plate,
wherein the support plate includes:
a chuck configured to support the substrate;
a plurality of heating lamps configured to emit light to heat the substrate supported on the chuck; and
a reflector,
wherein the reflector includes a curved surface configured to reflect the light generated by at least one of the heating lamps towards an edge region of the substrate supported on the chuck,
wherein the reflector includes:
a base disposed under the heating lamps; and
a protrusion protruding upward from the base,

wherein the protrusion includes the curved surface,
wherein the protrusion is arranged between an outermost heating lamp and an adjacent heating lamp to the outermost heating lamp, and
wherein the curved surface is configured to face a perimeter of the substrate,
wherein the protrusion includes:
a first protrusion including a first curved surface configured to reflect thermal energy toward a first position on the edge region of the substrate; and
a second protrusion including a second curved surface configured to reflect the thermal energy toward a second position on the edge region of the substrate, the second position being different from the first position.
