Patent ID: 8043432

Claim:
A deposition system for processing a plurality of substrates, the deposition system comprising: a process chamber including a first wall, a second wall spaced vertically from said first wall and oriented generally parallel with said first wall, and a peripheral sidewall extending from said first wall to said second walls to define a processing space; a substrate support disposed between said first and second walls and radially inside said peripheral sidewall, the substrate support configured to rotate the substrates relative to said peripheral sidewall about an axis of rotation, and said substrate support having a surface configured to hold the substrates; a plurality of partitions each extending radially from said axis of rotation toward said peripheral sidewall, said partitions dividing said processing space into a first compartment and a second compartment, and said second compartment configured to contain an inert atmosphere; and a first injector communicating through said peripheral sidewall with said first compartment, said first injector including a first plurality of injection ports configured to inject a first process material through said peripheral sidewall into said first compartment and a second plurality of injection ports configured to inject the first process material through said peripheral sidewall into said first compartment, said first plurality of injection ports arranged in a first plane disposed at a first height between said first wall and said substrate support, and said second plurality of injection ports arranged in a second plane at a second height above said surface of said substrate support that differs from the first height of the first plane, wherein said substrate support moves each of the substrates for sequential exposure of a top surface of each of the substrates to the first process material in said first compartment and the inert atmosphere in said second compartment.
