Abstract
Systems for and methods of laser-enhanced plasma processing of semiconductor materials are disclosed. The method includes supporting a semiconductor material in a processing chamber interior and subjecting the semiconductor material to a plasma process. The method also includes simultaneously heating the wafer surface with a laser beam through a window in the processing chamber to increase the reaction rate of the plasma process. Other methods include performing laser heating of the semiconductor material before or after the plasma process but while the semiconductor material resides in the same chamber interior.
