  • Patent number: 6543084
    Abstract: A brush core and the method for making a brush core for use in substrate scrubbing are provided. The substrate can be any substrate that may need to undergo a scrubbing operation to complete a cleaning operation, etching operation, or other preparation. For instance, the substrate can be a semiconductor wafer, a disk, or any other type of work piece that will benefit from a brush core that can deliver uniform controlled amounts of fluid through the brush along an entire length of the brush core. The brush core is defined by a tubular core having a length that extends between a first end and a second end. The first end has an opening into a bore that is defined through a middle of the tubular core and extends along an inner length of the tubular core. A first plurality of holes are oriented along a plurality of first lines that extend in the direction of the length of the tubular core, and each of the first plurality of holes define paths to the bore of the tubular core.

  • Publication number: 20030054730
    Abstract: A cover to be disposed over a substrate processing apparatus is provided. The cover includes a material capable of being tuned between an opaque state and a transparent state. Being tuned closer to the opaque state limits an amount of light capable of passing through the tunable cover and into the substrate processing apparatus during substrate processing. Being tuned closer to the transparent state allows viewing into the substrate processing apparatus without removing the cover.

  • Publication number: 20020061718
    Abstract: A method and system are provided for reducing and eliminating photo-assisted copper corrosion during a wafer cleaning process. In one example, a method is provided for making a composite material for the cover of a wafer cleaning system. A first transparent layer is formed. A transparency tunable layer is formed over the first transparent layer. Electrical connections are defined between a first portion and a second portion of the transparency tunable layer. And a second transparent layer is formed over the transparency tunable layer.

  • Patent number: 6187684
    Abstract: A method for post plasma etch cleaning a semiconductor wafer is provided. The semiconductor wafer has a plurality of layers formed thereon, and one of the plurality of layers is an oxide layer that has an overlying photoresist mask. The method includes plasma etching a via feature in the oxide layer. The plasma etching is configured to generate a polymer film on sidewalls of the via feature. An ashing operation is then performed to remove the photoresist mask. The method then moves to brush scrubbing the oxide layer and the via feature defined in the oxide layer with first chemicals in a first brush station. Brush scrubbing the oxide layer and the via feature follows with DI water in the first brush station. Then, the oxide layer and the via feature are brush scrubbed with second chemicals in a second brush station. In the same second brush station, the oxide layer and the via feature are scrubbed with DI water.
