Patent ID: 7498268

Claim:
A method of processing semiconductor substrates, the method comprising: placing a substrate on a substrate support in a chamber defining a processing region therein; introducing one or more process gases through at least one nozzle which extends into the chamber and which has a nozzle opening for the one or more process gases to flow therethrough; applying energy from a coil disposed outside the chamber to the processing region to perform a process on the substrate; and providing a heat shield for the nozzle, the heat shield being disposed within the chamber around at least a portion of the nozzle between the coil and the nozzle to reduce a temperature rise of the nozzle from the process performed on the substrate, the heat shield having an extension which projects distally of the nozzle opening of the nozzle and which includes a heat shield opening for the process gas to flow therethrough from the nozzle opening.
