An apparatus for heat treating semiconductor wafers is disclosed. The apparatus includes a heating device which contains an assembly linear lamps for emitting light energy onto a wafer. The linear lamps can be placed in various configurations. In accordance with the present invention, tuning devices which are used to adjust the overall irradiance distribution of the light energy sources are included in the heating device. The tuning devices can be, for instance, are lamps or lasers.

Heating configuration for use in thermal processing chambers

The present invention is generally directed to a system and process for rotating semiconductor wafers in thermal processing chambers, such as rapid thermal processing chambers and chemical vapor deposition chambers. In accordance with the present invention, a semiconductor wafer is supported on a substrate holder which, in turn, is supported on a rotor. During processing, the rotor is magnetically levitated and magnetically rotated by suspension actuators and rotation actuators positioned outside of the chamber.

Method and system for rotating a semiconductor wafer in processing chambers

An apparatus for heat treating semiconductor wafers in a thermal processing chamber using light energy is provided. In one embodiment, the apparatus contains a window located between the semiconductor wafer and the energy source. The window contains a member that defines at least one passage capable of being placed into communication with a coolant to cool the window and at least partially offset the &ldquo;first wafer effect&rdquo;. Additionally, in some embodiments, the window has a thickness greater than about 1 inch so that it can withstand pressures applied during wafer processing.
