    摘要: Improvements in the design of a low mass wafer holder are disclosed. The improvements include the use of peripherally located, integral lips to space a wafer or other substrate above the base plate of the wafer holder. A uniform gap is thus provided between the wafer and the base plate, such as will temper rapid heat exchanges, allow gas to flow between the wafer and wafer holder during wafer pick-up, and keep the wafer holder thermally coupled with the wafer. At the same time, thermal disturbance from lip contact with the wafer is reduced. Gas flow during pick-up can be provided through radial channels in a wafer holder upper surface, or through backside gas passages. A thicker ring is provided at the wafer holder perimeter, and is provided in some embodiments as an independent piece to accommodate stresses accompanying thermal gradients. A self-centering mechanism is provided to keep the wafer holder centered relative to a spider which is subject to differential thermal expansion.

    摘要: There is provided a chemical vapor deposition apparatus comprising a structure defining a chamber having an area for horizontal positioning of a substrate, and having chamber walls for conducting a flow of gas across a surface of the substrate, said chamber having a gas inlet extending generally laterally across the width of the chamber structure; and a gas injector abutting the chamber structure adjacent said inlet, and including a plurality of gas supply passages, a gas inlet manifold connected to each of said passages, a separately adjustable metering valve apportioning flow through each of said passages, each of said passages having an outlet portion configured to cause the gas flow through the passage to diverge laterally into an expanded gas stream separated from adjacent streams, said injector further including walls that direct the gas streams into generally flat in edge-to-edge relation towards said chamber gas inlet, said chamber inlet being without partitions dividing the streams so that an edge of any one stream can mix with an edge of an adjacent stream.
