Abstract:
A wafer holder and temperature controlling arrangement has a metal circular wafer carrier plate, which covers a heater compartment. In the heater compartment a multitude of heater lamp tubes is arranged, which directly acts upon the circular wafer carrier plate. Latter is drivingly rotatable about the central axis. A wafer is held on the circular wafer carrier plate by means of a weight-ring residing upon the periphery of a wafer deposited on the wafer carrier plate.
