    Abstract: A method of making an electrostatic chuck comprising positioning a plate into a channel in a body to form a plenum and inserting a dielectric component into an opening in the plate, where the dielectric component defines a portion of a passage from the plenum. Thereafter, depositing a dielectric layer covering at least a portion of the body and at least a portion of the plate to form a support surface. The dielectric layer is polished to a specified thickness. In one embodiment, the polishing process forms an opening through the dielectric layer to enable the dielectric component to define a passage between the support surface and the plenum. In another embodiment, at least a portion of the dielectric layer is porous proximate the dielectric component such that the porous dielectric layer and the dielectric component form a passage between the support surface and the plenum. In a further embodiment, a hole is formed through the dielectric layer and the hole in the dielectric layer and the dielectric component form a passage between the support surface and the plenum.

    Abstract: A substrate support utilized in high-density plasma chemical vapor deposition (HDP-CVD) processing functions as a radio frequency (RF) electrode (e.g., a bias RF cathode). An upper surface of the substrate support has a central upper surface portion and a peripheral upper surface portion, with the peripheral upper surface portion recessed relative to the central upper surface portion. The upper surface of the support extends beyond an outer edge of the substrate when the substrate is positioned on the substrate support. This extension in the support upper surface may enhance process performance by reducing electric field edge effects, as well as by improving directional distribution of ions traveling to the substrate. Since the peripheral upper surface portion is recessed relative to the central upper surface portion, a detachable shield can be disposed on the peripheral upper surface portion for preventing undesirable deposition on, or chemical attack of, the peripheral upper surface is portion, without interfering with positioning of the substrate.

    Abstract: The present invention is directed to improving defect performance in semiconductor processing systems. In specific embodiments, an apparatus for processing semiconductor substrates comprises a chamber defining a processing region therein, and a substrate support disposed in the chamber to support a semiconductor substrate. At least one nozzle extends into the chamber to introduce a process gas into the chamber through a nozzle opening. The apparatus comprises at least one heat shield, each of which is disposed around at least a portion of one of the at least one nozzle. The heat shield has an extension which projects distally of the nozzle opening of the nozzle and which includes a heat shield opening for the process gas to flow therethrough from the nozzle opening. The heat shield decreases the temperature of nozzle in the processing chamber for introducing process gases therein to reduce particles.
