Latest Patents

One of William's notable patents is an **Apparatus for Chemical Mechanical Polishing**. This invention details a method and apparatus designed for polishing the face of a semiconductor wafer. The unique system involves a tooling head that holds the wafer securely in position while it is contacted by an abrasive pad. Movement is facilitated by a table where the abrasive pad is fixedly attached, allowing both to move in alignment with the wafer's surface. The innovation includes a controller that regulates the table’s motion according to a pre-defined polishing pattern, maintaining a constant velocity between the wafer and the pad. Additional features such as a circular platen, retention ring, adjustable coupling, and flexible disk enhance the effectiveness of the polishing process.

Another significant patent by William is also an **Apparatus for Chemical Mechanical Polishing** but focuses on the structural adaptations of the polishing assembly. This apparatus contains a table with a planar polishing surface that accommodates a polishing medium and a wafer carrier assembly to firmly hold the wafer against the polishing surface. Its design ensures that the wafer carrier does not rotate relative to the polishing table, providing a controlled polishing action as the wafer undergoes relative movement across the polishing surface.
