In one aspect, a method for cleaning an edge of a substrate is provided. The method comprises employing one or more rollers of a first diameter to rotate a substrate; contacting an edge of the substrate with one or more rollers of a second diameter that is larger than the first diameter; and cleaning the edge of the substrate using the one or more rollers of the second diameter. Numerous other aspects are provided.

Embodiments of the invention generally relate to apparatus and methods for cleaning chamber components using a cleaning plate. The cleaning plate is adapted to be positioned on a substrate support during a cleaning process, and includes a plurality of turbulence-inducing structures. The turbulence-inducing structures induce a turbulent flow of cleaning gas while the cleaning plate is rotated during a cleaning process. The cleaning plate increases the retention time of the cleaning gas near the showerhead during cleaning. Additionally, the cleaning plate reduces concentration gradients within the cleaning plate to provide a more effective clean. The method includes positioning a cleaning plate adjacent to a showerhead, and introducing cleaning gas to the space between the showerhead and the cleaning plate. A material deposited on the surface of the showerhead is then heated and vaporized in the presence of the cleaning gas, and then exhausted from the processing chamber.

Embodiments disclosed herein generally relate to an HVPE chamber. The chamber may have one or more precursor sources coupled thereto. For example, a gallium source and a separate aluminum source may be coupled to the processing chamber to permit gallium nitride and aluminum nitride to be separately deposited onto a substrate in the same processing chamber. The nitrogen may be introduced to the processing chamber at a separate location from the precursors and at a lower temperature. The chamber has a truncated box shape formed by a curved cover which improves the flow of the nitrogen and precursor gases and the uniformity of the film deposition.

Embodiments of the present invention relate to semiconductor device manufacturing, and more particularly to a horizontal megasonic module for cleaning substrates. In one embodiment an apparatus for cleaning a substrate is provided. The apparatus comprises a tank adapted to contain a cleaning fluid, a movable housing having a first side adapted to be placed in the cleaning fluid, a plurality of rotatable rollers coupled to the first side of the housing, the rollers positioned and including grooves to securely hold the substrate in a horizontal orientation, and one or more transducers adapted to direct vibrational energy through the cleaning fluid in the tank toward the substrate, wherein at least one of the transducers directs vibrational energy toward the substrate and substantially parallel to a major surface of the substrate.
摘要:
A method and apparatus for plasma processing of substrates in a substantially vertical orientation is described. Substrates are positioned on a carrier comprising at least two frames oriented substantially vertically. The carrier is disposed in a plasma chamber with an antenna structure positioned between the substrates. Multiple plasma chambers may be coupled to a transfer chamber with a turntable for directing the carrier to a target chamber. A loader moves substrates between the carrier and a load-lock chamber in which substrates are staged in a substantially horizontal position.

Embodiments of the present invention relate generally to lithium-ion batteries, and more specifically, to batteries having integrated separators and methods of fabricating such batteries. In one embodiment, a lithium-ion battery having an electrode structure is provided. The lithium-ion battery comprises an anode stack, a cathode stack, and an integrated separator formed between the anode stack and the cathode stack. The anode stack comprises an anodic current collector and an anode structure formed over a first surface of the anodic current collector. The cathode stack comprises a cathodic current collector and a cathode structure formed over a first surface of the cathodic current collector. The integrated separator comprises a first ceramic layer, a second ceramic layer, and a polymer material layer deposited between the first ceramic layer and the second ceramic layer.

Embodiments of the present invention generally relate to apparatus and methods for uniformly heating substrates. The apparatus include a transferable puck having at least one electrode and a dielectric coating. The transferable puck can be biased with a biasing assembly relative to a substrate, and transferred independently of the biasing assembly during a fabrication process while maintaining the bias relative to the substrate. The puck absorbs radiant heat from a heat source and uniformly conducts the heat to a substrate coupled to the puck. The puck has high emissivity and high thermal conductivity for absorbing and transferring the radiant heat to the substrate. The high thermal conductivity allows for a uniform temperature profile across the substrate, thereby increasing deposition uniformity. The method includes disposing a light-absorbing material on an optically transparent substrate, and radiating the light-absorbing material with a radiant heat source to heat the optically transparent substrate.
