● Founded company in 1990, pursuing it full time by the end of 1991.

● Responsible for overall corporate management, vision, strategic planning, technical direction, budgeting, new product development, and lithography research. Grew the company from one person and $60,000 in revenue in 1990 to 25 people and $2.5M in revenue in 2000.

● Developed the industry standard PROLITH Toolkit of lithography simulation software and the ProDATA suite of data analysis software.

● Provided consulting services to the semiconductor industry.

● Taught numerous short courses on optical lithography.


8/90 – 12/91 Lithography Engineer

● As an assignee of the department of defense to SEMATECH, provided lithography expertise to SEMATECH on a variety of different projects, including modeling and process development for deep-UV resist systems, processes optimization of the i-line production process, advanced development activities in phase-shifting mask technologies, and lithographic lens design.

● Taught short-term and long-term courses on lithography to SEMATECH staff and assignees.

National Security Agency , Fort Meade, MD

11/82 – 8/90 Senior Engineer - Lithography

● As a member of the Microelectronics Research Laboratory (MRL), was tasked with performing research for present and future agency needs in the area of microlithography for semiconductor processing. This work provided a unique blend of theoretical research (e.g., a mechanism for the development reaction, diffraction theory for proximity printing and aerial imaging) and experimental work (measurement of resist properties, model verification). Performed numerous practical and theoretical studies, e.g., resist coating uniformity on wafer tracks, mask bias effects for step-and-repeat printing, exposure optimization, image reversal techniques, and focus effects for submicron lithography. The results of this work have been published in numerous journals and presented at technical conferences, including invited papers at international conferences in Japan and Europe.
