Abstract
A chuck for heating and clamping a workpiece, such as a semiconductor workpiece, is disclosed. The chuck is configured to allow the workpiece to be heated to temperatures in excess of 600° C. Further, while the workpiece is heating, the components that make up the chuck may be maintained at a much lower temperature, such as room temperature. The chuck includes a housing, formed as a hollow cylinder with sidewalls and an open end. Electrodes are disposed at the top surface of the sidewalls to clamp the workpiece. A heat source is disposed in the cavity and emits radiated heat toward the workpiece. A clamp ring may be used to secure the workpiece. In some embodiments, a thermal sensor is used to monitor the temperature of the workpiece.
