The present invention generally relates to a gas distribution showerhead and a shadow frame for an apparatus. By extending the corners of the gas distribution showerhead the electrode area may be expanded relative to the anode and thus, uniform film properties may be obtained. Additionally, the expanded corners of the gas distribution showerhead may have gas passages extending therethrough. In one embodiment, hollow cathode cavities may be present on the bottom surface of the showerhead without permitting gas to pass therethrough. The shadow frame in the apparatus may also have its corner areas extended out to enlarge the anode in the corner areas of the substrate being processed and thus, may lead to deposition of a material on the substrate having substantially uniform properties.

A method for forming a semiconductor structure includes forming a plurality of features across a surface of a substrate, with at least one space being between two adjacent features. A first dielectric layer is formed on the features and within the at least one space. A portion of the first dielectric layer interacts with a reactant derived from a first precursor and a second precursor to form a first solid product. The first solid product is decomposed to substantially remove the portion of the first dielectric layer. A second dielectric layer is formed to substantially fill the at least one space.

摘要:
A method of forming and removing a sacrificial oxide layer is described. The method includes forming a step on a substrate, where the step has a top and sidewalls. The method may also include forming the sacrificial oxide layer around the step by chemical vapor deposition of molecular oxygen and TEOS, where the oxide layer is formed on the top and sidewalls of the step. The method may also include removing a top portion of the oxide layer and the step; removing a portion of the substrate exposed by the removal of the step to form a etched substrate; and removing the entire sacrificial oxide layer from the etched substrate.
