摘要:
The method and apparatus of the embodiments of the present invention employ an in-situ particle decontamination technique that allows for such decontamination while a wafer is a vacuum tool or deposition chamber, thereby eliminating the need for another device for performing decontamination. This in-situ decontamination is effective for particle contamination resulting, for example, from tool resident mechanical component. Furthermore, particle decontamination is performed in the presence of plasma, having a potential for helping to maximize a “self bias” voltage, under RF conditions, and is integrated into the vacuum process.
