摘要:
Embodiments of the present invention generally relate to an apparatus and method for uniform sputter depositing of materials into the bottom and sidewalls of high aspect ratio features on a substrate. In one embodiment, a sputter deposition system includes a collimator that has apertures having aspect ratios that decrease from a central region of the collimator to a peripheral region of the collimator. In one embodiment, the collimator is coupled to a grounded shield via a bracket member that includes a combination of internally and externally threaded fasteners. In another embodiment, the collimator is integrally attached to a grounded shield. In one embodiment, a method of sputter depositing material includes pulsing the bias on the substrate support between high and low values.
摘要:
Disclosed are method and apparatus for treating a substrate. The apparatus is a dual-function process chamber that may perform both a material process and a thermal process on a substrate. The chamber has an annular radiant source disposed between a processing location and a transportation location of the chamber. Lift pins have length sufficient to maintain the substrate at the processing location while the substrate support is lowered below the radiant source plane to afford radiant heating of the substrate. A method of processing a substrate having apertures formed in a first surface thereof includes depositing material on the first surface in the apertures and reflowing the material by heating a second surface of the substrate opposite the first surface. A second material can then be deposited, filling the apertures partly or completely. Alternately, a cyclical deposition/reflow process may be performed.

摘要:
The angular ion distribution in plasma processing is controlled using a bias voltage frequency. In one example, a plasma containing gas ions is generated in a plasma chamber. The plasma sheath is modified using an aperture disposed between the plasma sheath and the workpiece so that the plasma sheath takes a shape above the aperture. An oscillating radio frequency bias voltage is generated and applied to a workpiece holder. The workpiece holder applies the bias voltage to the workpiece to generate a workpiece bias voltage with respect to the plasma to attract ions across the plasma sheath toward the workpiece. The aperture and the frequency of the bias voltage control an angle at which the ions are attracted toward the workpiece.
