OBJECTIVE: To obtain a research, development or problem solving position in a company where I will be a

key contributor to their manufacturing process. The ideal position would involve managerial responsibility.

SUMMARY: Process scientist whose most current work dealt with furnace processing of semiconductors.

Experience as process owner for both atmospheric and LPCVD processes. While at Intraspec, the process for

manufacturing a diode array was developed. In seven years with E.G. & G, several key problems were solved

which made the product line for their nuclear radiation detectors significantly better. Excels in thorough studies

of problems which result in solutions and not quick fixes.

PROFESSIONAL EXPERIENCE

ST Microelectronics, Phoenix Arizona 2000-2009

Engineer IV

Process owner for Polysilicon, Silicon Nitride, and HTO Deposition at a BICMOS fab.

Experience with TEL Alpha 8-SE, SVG VTR and AVP furnaces.

Earned Quarterly achievement award for solving high sheet rho problem in polysilicon films.

Maintained high CPk for poly deposition in multi product fab.

White Oak Semiconductor, Richmond Virginia 2000-(10/2000)

Diffusion Process Engineer

Process Owner for Oxidation Processes, including sacrificial oxide, gate oxide, anneals, and

diffusions.

Maintained control charts and developed process recipes for DRAM processes. First position was

Process Owner for metal anneals, backend anneals and polyimide cures.

Silicon Valley Group, Inc., Richmond Virginia 1998-2000

Senior Field Process Support Engineer

Qualified diffusion furnaces for semiconductor manufacturing. Experience with model based

temperature control of furnaces. Solved problems which arose in manufacturing processes at customer

sites. Wrote processes which will be used by company to test furnaces in other manufacturing sites.

E.G. &G. Instruments, Oak Ridge, Tennessee 1997-1998

Research Scientist

Set up laboratory for transferring electrochemical division research lab from New Jersey to Tennessee.

Ran corrosion, and electrochemical impedance tests on various samples in order to test software and

instruments. Defined experimental procedure and data analysis for new software which will allow

testing semiconductor electrochemical cells (Mott-Schottky analysis).

INTRASPEC INC., Oak Ridge, Tennessee 1995-1997

Research Scientist

Developed lithographic process for the manufacture of segmented neutron radiation detectors on high

resistivity silicon.

Oversaw repair of mask aligner and developed capacitance voltage procedures for measuring the

quality of oxide grown on substrates.

E.G.&G. ORTEC, Oak Ridge, Tennessee 1988-1995

Staff Scientist in Detector R&D

Researched and solved problems with nuclear radiation detectors. Evaluated process changes on

germanium gamma ray detectors as the responsible engineer of a multi-million dollar business.

Transferred new technologies into manufacturing process in order to improve the product.

Documented procedure for detector manufacturing so that company could get ISO-9000

certification.

Designed and oversaw the manufacture of a complete hybrid first stage for coaxial detector

systems. Detectors with hybrid electronics had improved high count rate performance 15%,

electronic noise 10%.

Developed a plug-in socket for use with hybrid electronics. Allows easier manufacture and repair

of detector.

Identified an alternative to trichloroethylene for cleaning components used in the manufacture of

germanium detectors. Cleaning costs could be lowered 80%.

Developed getter insert for use in detector systems. Calculated mean time to failure due to

vacuum problems increased from one year to greater than five years.

Developed new process for passivating germanium detectors.

Identified and solved several problems in the manufacturing process which had caused decreased

yields.

NORTH CAROLINA STATE UNIVERSITY, Raleigh, North Carolina 1984-1988

MICROELECTRONICS CENTER OF NORTH CAROLINA

Research Associate 1984-1988

Researched high temperature etching of silicon wafers. Served as the assistant laboratory manager to

the silicon wafer processing lab, a complete clean room laboratory designed to permit the manufacture

of integrated circuits from the design stage to the finished product.
