Method and apparatus for cooling a resonator of a megasonic transducer
摘要:
A method for cleaning a semiconductor substrate is provided. The method initiates with introducing a liquid onto the top surface of the semiconductor substrate. Then, a bottom surface of a resonator is coupled to a top surface of a semiconductor substrate through the liquid. Next, sonic energy is transmitted through the resonator to the liquid. Then, the liquid is heated through the bottom surface of the resonator. A method for applying localized heating to a cleaning chemistry during a cleaning operation of a semiconductor substrate is also provided. The method initiates with positioning a resonator to contact a surface of a cleaning chemistry applied to a semiconductor substrate. Then, heat energy is simultaneously applied with the sonic energy through the resonator to clean the semiconductor substrate. A device for cleaning a semiconductor substrate and system for cleaning a semiconductor substrate are also provided.
