Title: The Innovative Contributions of William Schaffer
Introduction
William Schaffer is a notable inventor based in Atascadero, California. He has made significant contributions to the field of thermal processing, holding a total of six patents. His work focuses on enhancing the efficiency and effectiveness of substrate processing, which is crucial in various technological applications.
Latest Patents
One of Schaffer's latest patents is a method of thermal processing structures formed on a substrate. This invention describes methods used to perform an annealing process on specific regions of a substrate. In one embodiment, energy is delivered to the surface of the substrate to preferentially melt certain desired regions. This process aims to remove unwanted damage created from prior processing steps, such as crystal damage from implant processes. Additionally, it helps to more evenly distribute dopants in various regions of the substrate and activate different areas. The preferential melting processes allow for a more uniform distribution of dopants in the melted region, due to the increased diffusion rate and solubility of the dopant atoms in the molten substrate. The creation of a melted region facilitates the redistribution of dopant atoms, the removal of defects from previous processing steps, and the formation of regions with hyper-abrupt dopant concentrations.
