Introduction

William Daniel Bevers is a notable inventor based in Orlando, FL (US). He has made significant contributions to the field of semiconductor technology, holding 2 patents that showcase his innovative approach to improving manufacturing processes.

Latest Patents

One of his latest patents is titled "In-situ removal of surface impurities prior to arsenic-doped polysilicon deposition in the fabrication of a heterojunction bipolar transistor." This patent describes a process for cleaning the silicon surface of a semiconductor device material layer. The surface undergoes a pre-clean process followed by exposure to a nitrogen-containing gas. A polysilicon layer is then formed on the surface in the same chamber and at about the same temperature as the cleaning and nitrogen exposing steps.

Another significant patent is "Bypass loop gas flow calibration." This invention outlines apparatuses, methods, and systems to monitor the performance of one or more mass flow controllers that supply gases to deposition, etching, and other manufacturing processes. A bypass loop is provided in fluid connection from either the process line or the vent line. In the bypass loop is a flow detector, such as a digitized mass flow controller. The flow detector takes one or more measurements of gas flow from a mass flow controller, and data from these measurements is used to provide information about the accuracy and/or precision of the mass flow controller. The patent also discloses ways to correct for back pressure or back vacuum in the process line.
