SAN FRANCISCO Graham Siddall has stepped down as executive chairman of automated test equipment supplier Credence Systems Corp., 10 months after being replaced as CEO, the company said Monday (Oct. 31).
Siddall also resigned from the company's board of directors, Credence (Milpitas, Calif.) said.
Siddall served as Credence president and CEO from 1999 until Jan. 1 of this year, when he was replaced by Dave Ranhoff.
In a statement issued by Credence Monday, Siddall said his retirement was part of a strategic succession plan developed by Credence executive management several years ago.
"My tenure at Credence has been exciting, demanding and challenging, but after 25 years in the semiconductor equipment industry, I'm looking forward to having more time to devote to my other interests," Siddall said.
Prior to joining Credence, Siddall was an executive with KLA-Tencor Corp. and, prior to the merger that created that company, Tencor Instruments.
