    摘要: The invention is embodied in a plasma reactor for processing a semiconductor wafer, the reactor having a gas distribution plate including a front plate in the chamber and a back plate on an external side of the front plate, the gas distribution plate comprising a gas manifold adjacent the back plate, the back and front plates bonded together and forming an assembly. The assembly includes an array of holes through the front plate and communicating with the chamber, at least one gas flow-controlling orifice through the back plate and communicating between the manifold and at least one of the holes, the orifice having a diameter that determines gas flow rate to the at least one hole. In addition, an array of pucks is at least generally congruent with the array of holes and disposed within respective ones of the holes to define annular gas passages for gas flow through the front plate into the chamber, each of the annular gas passages being non-aligned with the orifice.

    摘要: An electrostatic chuck provides reduced electric field effects about its peripheral edge. In one version, the chuck comprises a dielectric covering an electrode having a perimeter and a wire loop extending about the perimeter, the wire loop having a radially outwardly facing surface that is substantially rounded. Alternatively, the electrode may have a central planar portion comprising a top surface and a bottom surface, and a peripheral arcuate portion having a tip with a curvature length of at least about π/8 radians between a normal to the top surface of the central planar portion and a normal to the upper surface of the tip. The electrostatic chuck is used to hold a substrate in a process chamber of a substrate processing apparatus.

    摘要: A method and apparatus for controlling a temperature of a wafer during processing such as in a gas plasma or nonplasma environment wherein a wafer is positioned on a chuck. The wafer is heated and a pressurized gas is introduced into a space between the wafer and the chuck such that the pressurized gas transfers heat from the wafer to the chuck. Pressure of the pressuried gas is automatically varied such that heat transfer between the wafer and the chuck is varied in response to a difference between an actual wafer temperature and a desired wafer temperature to maintain the desired wafer temperature.
