Latest Patents

David Goodwin holds a patent for a "Wafer cleaning brush profile modification." This invention features a wafer cleaning brush roller that incorporates both uniform and non-uniform protrusions achieved through compression. The protrusions are created by an inner PVA sponge that is compressed through an outer sleeve made of a resilient mesh, which is non-reactive with deionized (DI) water or other chemical mechanical planarization (CMP) surfactants. Additionally, the design includes directional channeling of DI water to the protrusions, enhancing the cleaning capability. The brush also features thicker extensions at each end to effectively clean the edges of the wafer, where additional cleaning is often required.
