Title: Glenn J Tessmer: Innovator in Diamond Technology

Introduction

Glenn J Tessmer is a notable inventor based in Cary, NC (US), recognized for his contributions to diamond technology. He holds 2 patents that showcase his innovative approaches in the field.

Latest Patents

One of his latest patents is a method for etching a diamond film. This technique involves anisotropically etching a diamond film by selectively patterning a mask layer on its surface. The process includes subjecting the mask layer and exposed surface portions of the diamond film to a hydrogen-containing plasma while negatively biasing the diamond film. This method effectively converts the exposed surface portions of the diamond layer to nondiamond carbon, allowing for continuous removal of the nondiamond carbon and maintaining efficient electron emission for further etching.

Another significant patent is the microelectronic diamond capacitive transducer. This device features a first electrically conductive layer and a diamond diaphragm that is moveable relative to the first layer. The diamond diaphragm serves as the second plate for the transducer, with the first layer defining the first plate. The design includes a degeneratively doped diamond layer and an insulating layer that acts as an overpressure stop. This transducer can be configured for absolute or differential pressure sensing and may also function as an actuator.
