发明名称 Method of processing wafers with low mass support
摘要 A method is provided for treating wafers on a low mass support. The method includes mounting a temperature sensor in proximity to the wafer, which is supported on the low mass support, such that the sensor is only loosely thermally coupled to the wafer. A temperature controller is programmed to critically tune the wafer temperature in a temperature ramp, though the controller directly controls the sensor temperature. A wafer treatment, such as epitaxial silicon deposition, is started before the sensor temperature has stabilized. Accordingly, significant time is saved for the treatment process, and wafer throughput improved.
