    摘要: A substrate support having a removable edge ring, which is made of a material having a lower coefficient of thermal expansion (CTE), than that of the substrate support is provided. The edge ring and the substrate support are configured for pin and slot coupling. Specifically, either the edge ring, or the substrate support comprises a plurality of pins, and the other of the edge ring or the substrate support comprises a plurality of hollow regions or slots in which the pins may be inserted. The slots are at least as wide as a corresponding one of the plurality of pins and extend in the direction in which the substrate support expands and contracts during thermal cycling. Each of the slots extends a length which is sufficient to compensate for the difference between the CTE of the substrate support and the CTE of the edge ring, over the range of process temperatures to which the apparatus is exposed. Preferably the susceptor is made of aluminum, and the edge ring is made of ceramic. A restrictor gap may be defined between a surface of the substrate support and a surface of the purge ring so as to restrict a volume of purge gas flowing to an edge of a substrate positioned on the substrate support. The purge gas delivery channel may have an exposed outlet and may be upwardly angled to facilitate cleaning.

    摘要: The present invention provides exemplary apparatus and methods for processing substrates and for ensuring purge gases reach the substrate edge, including edges of JMF type wafers, to help prevent unwanted deposition thereon. One embodiment provides an apparatus for processing substrates which includes a chamber and a substrate support (13) disposed in the chamber. An edge ring (15) is disposed on the substrate support. The edge ring has a lip portion (30) which at least partially overhangs an upper surface (36) of the substrate support to define a gap (29) between the lip portion and the upper surface. In this manner, the edge ring is designed to form a gap which properly directs purge gases to edges of the substrate, including JMF type substrates.

    摘要: A plasma reaction chamber particularly suited for plasma-enhance chemical vapor deposition of titanium using TiCl.sub.4 as the precursor. The reactor includes a perforated showerhead faceplate and a perforated blocker plate within the showerhead to evenly distribute the atomized TiCl.sub.4. Both the showerhead faceplate and the blocker plate are made of solid nickel. RF power is applied between the showerhead faceplate and the heater pedestal supporting the wafer to excite the processing gas into a plasma. A shield ring is set on the periphery of the heater pedestal to confine the plasma to the processing region above the wafer. The shield ring is supported on the heater pedestal by a downwardly descending ridge, thereby minimizing thermal flow. The shield ring also protects the periphery of the top surface of the heater pedestal not covered by the wafer. An isolator electrically insulates the RF-driven showerhead from the chamber body and is disposed generally above the shield ring. The bottom of the isolator and the top of the shield ring are similarly curved with a nearly constant gap between them. The small gap creates a flow choke between the processing region and an annular pumping channel. The curve of the gap prevents the plasma from extending into the pumping channel. The bottom of the chamber below the heater pedestal is covered with a quartz thermal shield insert to reduce the flow of heat to the chamber wall. A lift ring for raising lift pins selectively lifting the wafer is also composed of quartz.
