Faced with misconduct allegations, Lam Research Corp. CEO Martin Anstice resigned from Qualcomm’s board of directors on Dec. 4, according to a filing with the Securities and Exchange Commission.

Anstice also resigned from his post as chief executive of the Fremont-based semiconductor manufacturer on Dec. 5. Lam didn’t elaborate on the allegations, aside from specifying that Anstice’s departure was not due to financial misconduct.

”An integral part of the culture of Lam Research is our commitment to provide a safe and positive work environment where each of our employees has the opportunity to thrive,” Lam Independent Director Abhi Talwalkar said in a news release.

Anstice will not receive any severance benefits, according to a company statement.

Anstice had served on Qualcomm’s board for less than two months. He was appointed on Oct. 9, when Qualcomm expanded the number of board seats from 12 to 14. At the time, the company was fighting to gain the support of shareholders, who withheld voting support for Qualcomm’s proposed slate of directors in March.
