Title: The Innovative Contributions of Ashley Samuel Hull
Introduction
Ashley Samuel Hull is a notable inventor based in Saint Peters, MO (US). She has made significant contributions to the field of semiconductor manufacturing, holding 2 patents that showcase her innovative spirit and technical expertise.
Latest Patents
Her latest patents include a "Polishing apparatus, polishing head and method" and a "Method and apparatus for processing a semiconductor wafer using novel final polishing method." The polishing apparatus is designed for polishing semiconductor wafers and features a base, a turntable, a polishing pad, and a head drive mechanism for driven rotation of a polishing head. The polishing head includes a sealing ring that holds at least one wafer, allowing for the application of uniform air pressure over the rear surface of the wafer. This design ensures that the wafer itself defines a portion of a pressure cavity receiving pressurized air.
The second patent outlines a method of manufacturing a semiconductor wafer, which involves providing an ingot of semiconductor material, slicing the wafer, and processing it to enhance the parallelism of its surfaces. A final polishing operation is performed to prepare the front surface for integrated circuit fabrication, utilizing a unique approach that maintains the parallelism of both surfaces. Additionally, the wafer is rinsed with a fluid to increase hydrodynamic lubrication, and the patent includes methods for conditioning the polishing pad and handling wafers post-polishing.
