Alkyl push flow for vertical flow rotating disk reactors

In a rotating disk reactor for growing epitaxial layers on substrate or other cvd reactor system, gas directed toward the substrates at gas inlets at different radial distances from the axis of rotation of the disk has both substantially the same gas flow rate/velocity and substantially the same gas density at each inlet. The gas directed toward portions of the disk remote from the axis may include a higher concentration of a reactant gas than the gas directed toward portions of the disk close to the axis, so that portions of the substrate surfaces at different distances from the axis receive substantially the same amount of reactant gas per unit area, and a combination of carrier gases with different relative molecular weights at different radial distances from the axis of rotation are employed to substantially make equal the gas density in each region of the reactor. ...

Periphery purge shutter and flow control systems and methods

An arrangement of two shutters radially outward from an injector block and a susceptor onto which a wafer carrier is removably mounted are configured to provide a flowpath through a reactor chamber that does not exhibit a vortex, thereby reducing or eliminating buildup on the inside of the reactor chamber and facilitating large temperature gradient between the injector block and the wafer carrier. This can be accomplished by introduction of a purge gas flow at a radially inner wall of an upper shutter, and in some embodiments the purge gas can have a different chemical composition than the precursor gas used to grow desired epitaxial structures on the wafer carrier.. ...
