Patent ID: 8071916

Claim:
A wafer heating apparatus comprising: a plate-shaped member comprising a first principal surface and a second principal surface, wherein the first and second principal surfaces oppose one another, wherein the first principal surface is configured for mounting a wafer; resistive heating members on the second principal surface; power feeder terminals connected to the resistive heating members, wherein the power feeder terminals are configured for supplying electric power to the resistive heating members; a casing provided to cover the power feeder terminals on the second principal surface of the plate-shaped member; and a nozzle of which tip faces the second principal surface of the plate-shaped member for cooling the plate-shaped member, wherein a projected position of the tip of the nozzle as projected onto the second principal surface is located between the resistive heating members, wherein the projected position of the tip of the nozzle as projected onto the second principal surface is located between the power feeder terminals.
