    摘要: An effluent abatement system 200 that may be used to abate F2 gas content of effluent exhausted from a process chamber 35, such as effluent from a CVD chamber cleaning process includes a catalytic reactor 250 to reduce the content of F2 in the effluent 100. The system may further include a prescrubber 230 to add reactive gases to the effluent 100 and/or to treat the effluent 100 prior to treatment in the catalytic reactor 250. Alternatively reactive gases can be added to the effluent 100 by a gas source 220.

    摘要: A stand-off pad, and method of fabricating the same, for supporting a workpiece in a spaced apart relation to a workpiece support chuck. More specifically, the wafer stand-off pad is fabricated of a polymeric material, such as polyimide, which is disposed upon the support surface of the chuck. The stand-off pad maintains a wafer, or other workpiece, in a spaced apart relation to the support surface of the chuck. The distance between the underside surface of the wafer and the chuck is defined by the thickness of the stand-off pad. This distance should be larger than the expected diameter of contaminant particles that may lie on the surface of the chuck. In this manner, the contaminant particles do not adhere to the underside of the wafer during processing and the magnitude of the chucking voltage is maintained between the workpiece and the chuck.

    摘要: An electrostatic chuck (20) for holding a substrate (75) comprises (i) a base (80) having an upper surface (95) with grooves (85) therein, the grooves (85) sized and distributed for holding coolant for cooling a substrate (75), and (ii) a substantially continuous insulator film (45) conformal to the grooves (85) on upper surface (95) of the base (80). The base (80) can be electrically conductive and capable of serving as the electrode (50) of the chuck (20), or the electrode (50) can be embedded in the insulator film (45). The insulator film (45) has a dielectric breakdown strength sufficiently high that when a substrate (75) placed on the chuck (20) and electrically biased with respect to the electrode (50), electrostatic charge accumulates in the substrate (75) and in the electrode (50) forming an electrostatic force that attracts and holds the substrate (75) to the chuck (20). Preferably the chuck (20) is fabricated using a pressure forming process, and more preferably using a pressure differential process.
