Abstract: Embodiments described herein relate to a faceplate for improving film uniformity. A semiconductor processing apparatus includes a pedestal, an edge ring and a faceplate having distinct regions with differing hole densities. The faceplate has an inner region and an outer region which surrounds the inner region. The inner region has a greater density of holes formed therethrough when compared to the outer region. The inner region is sized to correspond with a substrate being processed while the outer region is sized to correspond with the edge ring.

Abstract: Embodiments of the invention relate generally to an ultraviolet (UV) cure chamber for curing a dielectric material disposed on a substrate and to methods of curing dielectric materials using UV radiation. A substrate processing tool according to one embodiment comprises a body defining a substrate processing region; a substrate support adapted to support a substrate within the substrate processing region; an ultraviolet radiation lamp spaced apart from the substrate support, the lamp configured to transmit ultraviolet radiation to a substrate positioned on the substrate support; and a motor operatively coupled to rotate at least one of the ultraviolet radiation lamp or substrate support at least 180 degrees relative to each other.

Abstract: The present invention is directed to the design of a plasma CVD chamber which provides more uniform conditions for forming thin CVD films on a substrate. In one embodiment, an apparatus for processing semiconductor substrates comprises a chamber defining a plasma processing region therein. The chamber includes a bottom, a side wall, and a dome disposed on top of the side wall. The dome has a dome top and having a side portion defining a chamber diameter. A top RF coil is disposed above the dome top. A side RF coil is disposed adjacent the side portion of the dome. The side RF coil is spaced from the top RF coil by a coil separation. A ratio of the coil separation to the chamber diameter is typically at least about 0.15, more desirably about 0.2-0.25.
