Title: Russell L Johnson: Innovator in Piezo-Resistive Technology
Introduction
Russell L Johnson is a notable inventor based in New Brighton, MN (US). He has made significant contributions to the field of piezo-resistive technology, holding a total of 8 patents. His work focuses on optimizing resistance in various sensing applications, showcasing his expertise and innovative spirit.
Latest Patents
One of Johnson's latest patents is a method and structure of ion implanted elements for the optimization of resistance. This invention involves a method of forming a piezo-resistive sensor that includes a piezo-resistor, a leadout resistor, and an insulator structure. The process utilizes a Silicon-On-Insulator (SOI) substrate with an epitaxial layer, dielectric layer, and bulk substrate layer. A mask layer is formed on the epitaxial layer to define the locations of the piezo-resistor and leadout resistors. Additionally, a silicon dioxide layer is grown using a Local Oxidation of Silicon (LOCOS) process to achieve the desired thickness of the piezo-resistor.
Another significant patent by Johnson is a pressure and temperature sensing element. This invention features a piezo-resistive sensing element configured as a single light implant square. It is capable of producing outputs related to both pressure and temperature. The piezo-sensing element can operate in two modes: as a piezo-resistive radial element or as a piezo-resistive tangential element, depending on the direction of the current conducted through it. The differences in resistances and corresponding voltage drops are proportional to the applied pressure, while the sum of the resistances functions as a temperature indicator.
