Title: The Innovative Contributions of Dale Du Bois
Introduction
Dale Du Bois is a notable inventor based in Los Gatos, California. She has made significant contributions to the field of semiconductor manufacturing through her innovative designs and patents. Her work focuses on enhancing the efficiency and effectiveness of wafer processing.
Latest Patents
Dale Du Bois holds a patent for a "Shadow ring for modifying wafer edge and bevel deposition." This invention contemplates a shadow ring that provides increased or decreased and more uniform deposition on the edge of a wafer. By removing material from the top and/or bottom surfaces of the shadow ring, increased edge deposition and bevel coverage can be realized. In one embodiment, the material on the bottom surface is reduced by providing a recessed slot on the bottom surface. By increasing the amount of material of the shadow ring, the edge deposition and bevel coverage is reduced. Another approach to adjusting the deposition at the edge of the wafer includes increasing or decreasing the inner diameter of the shadow ring. The material forming the shadow ring may also be varied to change the amount of deposition at the edge of the wafer.
