In his 27 year research career at Texas Instruments, he developed many chemical processes. This included the methods of measuring and monitoring those semiconductor processing and processing related chemistry.
The instrumentation ranged from sophisticated electro-optical and laser technology for examination of photoresist exposure to simple sampling methods for waste water monitoring.
He was a pioneer in the development of plasma processing for semiconductor manufacturing and patentee for all Expert processing. Outside of TI, he cofounded a sucessful company that invented and developed a microwave instrument to measure water in petroleum.

Other than analytical instruments he has also invented, designed and implemented other types of chemical instruments. A safety need for a on demand Arsine generator for Gallium Arsenide epitaxy, led him to invent and patent an electrochemical Arsine generator. In a more research mode, he invented a real time flow through microreactor for measuring kinetics with video analysis. He also developed a method and built an instrument for measuring the interaction of polymers by measuring the influence of viscous shear on flourescence.

A primary function of his research position at Texas Instruments was to develop and improve processing of semiconductors. He was the first to build in house poly-silicon deposition, and later installed and set up the first external poly and silicon nitride reactors in the developmental front end. In metal etch, he developed with outside vendors the first acid resistant surfactants.
He invented and developed the first plasma etching reactors and concieved and implemented processes for devices spanning CCDs, MOS, and exotic ICs. His plasma aluminum etch was held trade secret for many years.
The development of a photolithographic laser writer was a significant achievement. This device was capable of direct writing micron wide lines over large areas in minutes. Several versions of this laser writer were made for making state of the art high density circuits, and microwave devices.

He analyzed existing processes and defined modifications for Potato Chip manufacturing.He researched and instrumented a new methodology for making stronger concrete.He lead the development and implementation of new high tech packaging machinery.He formulated an efficient new industrial deodorant.He was co-inventor of a Marksmanship Device.
"Point and Shoot" Laser aiming device.
