GMT Microelectronics Corporation (GMT stands for Great Mixed-signal
Technologies) was an independent, privately held,
silicon wafer foundry and analog, mixed-signal and power management integrated
circuits.
When the Commodore Semiconductor Group closed its manufacturing plant in
1992. With the discovery of extensive contamination from leaking underground
storage tanks at the facility, the EPA ordered groundwater cleanup and other
related work. This was not completed as Commodore Business Machines went
bankrupt.
In December 1994, EPA entered into a Prospective Purchase Agreement (limited
the company's liability in exchange for sharing the costs of cleanup) with GMT
Microelectronics,
which enabled GMT to
purchase the facility from the bankrupt Commodore Business Machine, Inc. Operations at the
facility were restarted in January 1995.
Process, equipment improvements, and aggressive technical staffing enabled
GMT to initiate a production in May 1995. GMT’s fab had a capacity of producing
100mm and 125mm wafers in its 150,000 square foot facility, Dennis Peasenell was
Chairman and CEO and by 1999, GMT had $21.1 Million in revenue and 183 Employees.
However, GMT experienced financial difficulties and the EPA shutdown GMT operations in
2001. GMT ceased operations and its semiconductor assets were liquidated.
