    摘要: Methods and apparatus for controlling film deposition using a linear plasma source are described herein. The apparatus include a showerhead having openings therein for flowing a gas therethrough, a conveyor to support one or more substrates thereon disposed adjacent to the showerhead, and a power source for ionizing the gas. The ionized gas can be a source gas used to deposit a material on the substrate. The deposition profile of the material on the substrate can be adjusted, for example, using a gas-shaping device included in the apparatus. Additionally or alternatively, the deposition profile may be adjusted by using an actuatable showerhead. The method includes exposing a substrate to an ionized gas to deposit a film on the substrate, wherein the ionized gas is influenced with a gas-shaping device to uniformly deposit the film on the substrate as the substrate is conveyed proximate to the showerhead.

    摘要: A plurality of RF power signals have the same RF frequency as a reference RF signal and are coupled to respective RF connection points on an electrode of a plasma chamber. At least three of the RF connection points are not collinear. At least two of the RF power signals have time-varying phase offsets relative to the reference RF signal that are distinct functions of time. Such time-varying phase offsets can produce a spatial distribution of plasma in the plasma chamber having better time-averaged uniformity than the uniformity of the spatial distribution at any instant in time.
