Expert Details

Microelectronics Processing and Contamination Control, Cleanrooms, Particulates, Ultra High Purity

ID: 714244 New Mexico, USA

Request Expert

Expert has twenty years of research experience in semiconductor technology in major industrial laboratories. This, combined with his expertise gained by fifteen years managing microelectronics laboratories where he performed semiconductor fabrication research at two major universities (Minnesota and Arizona), makes him ideally suited to bringing new approaches to solving semiconductor manufacturing problems. He has consulted in industry on yield management issues and is an expert on contamination control and trace gas contamination issues (ppm vs. ppb vs. ppt). He worked as a Senior Quality Engineer for IBM and performed original research in silicon and III-V epitaxy at David Sarnoff Laboratories. He is an expert in CMOS fabrication and oxide evaluation.

Currently active in the new field MEMS (Micro Electro Mechanical Systems), he explores improvements to large aperture telescopes (CFH Hawaii, four meter at Kit Peak) using deformable mirror and adaptive seeing technologies.

Expert is very knowledgeable in the specialized purification, distribution, and analysis of high purity semiconductor grade chemicals, bulk and specialty gases for high technology applications. He is knowledgeable of "ultra clean" preparation of gate oxide and epitaxial growth surfaces.

He has built several ultra "Class 1" cleanroom facilities for advanced semiconductor R&D. He is also active in the contamination control research community.

Expert works well with attorneys on intellectual property issues and has extensive experience in Federal Court for high technology litigation as an expert witness. He performs both on-site and off-site consulting activities, both in the U.S. and abroad.
