    Abstract: A CVD reactor includes separate reaction and pressure chambers, where the reaction chamber is contained within and isolates reactant gases from the pressure chamber. The reactor also includes a gas injection system which injects process gas(es) into the reaction chamber in a somewhat vertical direction through a bottom surface of the reaction chamber. The gas injection system injects hydrogen or other appropriate gas in a vertical direction through the bottom surface of the reaction chamber. The flow of hydrogen or other appropriate gas is intermediate the flow of the process gas(es) and a surface of the reaction chamber, thereby re-directing the process gas flow parallel to the top surface of a wafer therein. In this manner, the reaction chamber does not require a long entry length for the process gas(es). This flow of hydrogen or other suitable gas also minimizes undesirable deposition on the surface of the reaction chamber.

    Abstract: A programmable multizone fluids injector for use in single-wafer semiconductor processing equipment including an injector having a plurality of orifices therein which are divided into a number of separate zones or areas. These zones or areas are connected by means of appropriate passageways and conduits to a source of process fluids. Each of the separate conduits has at least one flow control device located therein for independently controlling the amounts and ratios of process fluids flowing into each zone. The fluid control devices are responsive to input signals so that the fluid flow rates from the orifices can maintain a desired flow pattern within the process chamber to suit the individual needs of a particular fabrication processs.

    Abstract: An actively cooled effuser for a vapor deposition reactor is placed in very close proximity to a substrate. The actively cooled effuser has combinations of gas directing plates, cooling plates and isolation plates attached together. Reactants and coolant are input into the stack of plates so formed. Selective heating of the substrate surface may occur through the use of heating lamps. Multiple units of the actively cooled effuser and heating lamps may be used in the reactor to form multiple layers on the substrate. The cooling plate has a cooling channel within a few thousandths of an inch of the output side of the stack. The presence of the cooling plates allows the effuser to be placed in very close proximity to the selectively heated substrate.
