SAN FRANCISCO Jon Tompkins, former chairman and CEO of fab equipment supplier KLA-Tencor Corp., resigned from the company's board of directors Dec. 21, according to a filing made with the U.S. Securities and Exchange Commission (SEC) Wednesday (Dec. 27).
The reasons for Tompkins' departure were not specified in the SEC filing. A KLA-Tencor spokesperson told EE Times that Tompkins resigned for personal reasons, adding that he has been on the board for a long time and is 65 years old.
Tompkins is the fourth person to abruptly sever ties with KLA-Tencor since the company was implicated in a scandal over historical stock options grants. In October, KLA-Tencor announced the retirement of Kenneth Levy, founder and chairman.
Also in October, as part of an internal stock options investigation, KLA-Tencor terminated all aspects of its employment relationship with Kenneth Schroeder, the company's CEO from 1999 through 2005. At that time, KLA-Tencor announced that Stuart Nichols, the company's general counsel since 2000, had resigned. The company also said at that time that it expects to take a charge of up to $400 million related to improper stock options grants.
Tompkins served as CEO of KLA-Tencor from April 1997 until June 1998 and served as chairman of the board of KLA-Tencor from July 1998 until his retirement in 1999. He served as president and CEO of Tencor Instruments from April 1991 until its merger with KLA Instruments in April 1997. Tompkins is also chairman of the board of Electro Scientific Industries Inc. and a member of the boards of directors of Cymer Inc. and Credence Systems Corp.
