    摘要: PURPOSE: An in-situ preclean before an epitaxy is provided to remove the oxide from a silicon surface from the low temperature, thereby reducing the total operation cost. CONSTITUTION: A processing chamber(310) maintains a substrate. A heating source heats up the substrate in the processing chamber. A gas source(390) supplies the Ge source vapor and etchant source vapor to the processing chamber. At least one controller(350,400) comprises a memory and a processor. The controller performs a plurality of cleaning cycle.
