Patent ID: 8796594

Claim:
A semiconductor manufacturing equipment comprising: a heater including a heater element part, a first connection part and a second connection part, wherein the heater element part is configured to heat a wafer from a rear surface of the wafer, and the first connection part and the second connection part are integrated with the heater element part, and are projected from a rear surface of the heater element part; a first electrode contacted with and fixed to the first connection part, and configured to apply a voltage to the first connection part, wherein a first contact surface between the first electrode and the first connection part is perpendicular to the rear surface of the heater element part; and a second electrode contacted with and fixed to the second connection part, and configured to apply a voltage to the second connection part, wherein a second contact surface between the second electrode and the second connection part is respectively perpendicular to the rear surface of the heater element part and the first contact surface wherein the first connection part and the first electrode are movable in the first contact surface; and the second connection part and the second electrode are movable in the second contact surface.
