Abstract:
A reactor for deposition of a film on a surface of each of a plurality of wafers, said reactor comprising:(a) a first chamber having an interior for placement of a wafer boat for processing a plurality of wafers, said chamber further including(i) a chamber wall having a window for transmission of radiant heat energy from the exterior of said chamber through said window to said interior for heating said plurality of wafers;(ii) a thermal plate positioned between said window and said interior for diffusing said heat energy for heating said wafers on said boat;(b) radiant heater apparatus positioned exterior of said first chamber for radiating said heat energy through said window to said interior for heating said thermal plate;(c) positioning apparatus for positioning said wafer boat in the first chamber, the wafer boat capable of holding a plurality of wafers in a vertical stack arrangement, the wafer boat including a plurality of RF plates and a plurality of susceptors, wherein each of the plurality of wafers is positioned with a flat deposition surface oriented horizontally, each wafer on a susceptor beneath an RF plate, each susceptor connected to a connection apparatus for connecting to a first side of an RF power supply, and each RF plate connected to a connection apparatus for connecting to a second side of said RF power supply;(d) injector apparatus for introducing a reactant gas mixture to the first chamber, said injector apparatus for injecting reactant gas directed parallel to each said deposition surface of each wafer upon which said film is to be deposited; and(e) exhaust apparatus for exhausting the gas mixture from the first chamber, said exhaust apparatus for pulling said injector reactant gas parallel to each said deposition surface and colinear with a direction of said injected gas, said exhaust apparatus positioned opposite said boat from said injector apparatus.
