WCQ Announces New Silicon Operations Director, Zbigniew Radzimski, Ph.D.

SAN FRANCISCO--(Business Wire)--
West Coast Quartz Corporation (WCQ), a privately held and globally-renowned
manufacturer of silicon crystal for the semiconductor and solar industries as
well as premier fabricator of precision quartz and silicon components for
semiconductor wafer process equipment, today announced Zbigniew Radzimski,
Ph.D., as the Company`s Silicon Operations Director.

Dr. Radzimski taught as a Professor in the Material Science and Engineering Dept
of NC State from 1986 to 1997, then took a position from 1997 to 2004 in the
Office of the President/CEO of Shin-Etsu Handotai America, key division of the
largest silicon wafer company in the world, and then moved to Silicon Quest
International, a specialty silicon wafer company, from 2004 until May 2009,
where he completed a term as President of the company.

"We have known Dr. Radzimski for many years, and we are exceedingly pleased to
have him join WCQ leadership," commented WCQ President Paul Maloney. "After
expanding our silicon crystal growing division in both Czochralski (CZ) as well
as Bridgman methods across two crystal growing facilities, it was time to bring
in a seasoned and well-reasoned materials and management expert to guide us to
the next level and next geometries."

WCQ grows multi-crystalline silicon in two sizes, 660x660x220mm and
840x840x240mm, and WCQ grows mono-crystalline silicon in custom diameters
ranging up to 450mm for existing customers. Single crystal growing larger than
500mm diameter is under development at the Company.
