Latest Patents

Yushin Son holds a patent for a method titled "Method for chemical mechanical polishing using synergistic geometric patterns." This invention outlines a process for planarizing the surface of a wafer against a polishing pad. The method involves securing the wafer in a carrier, pressing it against the polishing pad, rotating both the wafer and pad, and moving the wafer across the pad to create geometric patterns. Notable patterns include a 'figure eight', an elliptical pattern, and a peanut-shaped pattern. The use of Bezier splines in this method allows for efficient data storage and transfer, requiring only two endpoints and two control points to represent the entire curve.
