Title: Herbert V Wong: Innovator in High Temperature Pressure Transducers
Introduction
Herbert V Wong is a notable inventor based in San Francisco, CA, recognized for his contributions to the field of pressure transducers. With a total of 3 patents, Wong has made significant advancements in the production of silicon diaphragm pressure transducers that operate effectively in high-temperature environments.
Latest Patents
Wong's latest patents focus on high temperature layered silicon structures. The first patent describes a process for producing silicon diaphragm pressure transducers that can function in high temperature applications exceeding 150°C. This innovation involves properly insulating the strain gauges from the diaphragm by utilizing two oriented silicon wafers joined through a two-step diffusion technique. This method includes the diffusion bonding of a boron-doped wafer surface into another oxide-coated wafer surface at reduced pressures and temperatures. The simultaneous diffusion process is enhanced by contouring one of the bonded surfaces, which allows for a continuous diffusion of boron into the boron oxide coated surface, resulting in a uniform boron-rich layer. The process also incorporates mechanical lapping and selective etching, yielding a level boron-rich surface ready for further processing. This invention notably simplifies fabrication, thereby reducing the overall cost of the final transducer.
