Latest Patents
Cheng's latest patents include a "Polishing pad with offset concentric grooving pattern and method for polishing a substrate therewith." This invention provides a polishing pad designed for chemically-mechanically polishing a substrate. The polishing pad features a plurality of grooves, including at least a first plurality of concentric grooves with a unique center of concentricity, and a second plurality of concentric grooves with a different center of concentricity. Notably, the first and second centers of concentricity do not coincide, and the axis of rotation of the polishing pad is not aligned with either center. Additionally, the grooves do not form a continuous spiral pattern, and the polishing surface avoids a mosaic groove pattern.
Another significant patent is the "CMP polishing pad having edge exclusion region of offset concentric groove pattern." This invention also focuses on a polishing pad and its method of use for chemically-mechanically polishing a substrate. The design includes a grooved region and an exclusion region, which is located adjacent to the circumference of the polishing pad and is devoid of grooves.
