Abstract:
1. A reactor for vapor deposition of a material onto a microelectronic workpiece having an inner region and an outer region radially outward from the inner region, comprising: a reaction chamber having an inlet and an outlet; and a gas distributor in the reaction chamber, the gas distributor having a plenum through which a gas can flow along a flow path, the plenum having a distributor plate transverse to the flow path, and the distributor plate having a plurality of passageways extending through the plate, the passageways including first passageways having a first physical parameter and extending through the plate at an oblique angle relative to a plane defined by the plate and second passageways having a second physical parameter different than the first physical parameter and extending through the plate at an angle substantially perpendicular to the plane, and wherein the first passageways are in an inner region of the plate to supply the gas to the inner region of the microelectronic workpiece and the second passageways are in an outer region of the plate to supply the gas to the outer region of the microelectronic workpiece.
