Securities Exchange Act
Rule 12h-3

January 29, 2010

Response of the Office of Chief Counsel
Division of Corporation Finance

Based on the facts presented, the Division will not object if Semitool stops filing periodic and current reports under the Securities Exchange Act of 1934, including its quarterly report on Form 10-Q for the quarter ended December 31, 2009. In reaching this position, we note that Semitool has filed post-effective amendments removing from registration unsold securities under all effective registration statements on Form S-8, and those post-effective amendments are effective. We assume that, consistent with the representation made in your letter, Semitool will file a certification on Form 15 making appropriate claims under Exchange Act Rules 12g-4 and 12h-3 on or before the due date of its Form 10-Q for the quarter ended December 31, 2009.

This position is based on the representations made to the Division in your letter. Any different facts or conditions might require the Division to reach a different conclusion. Further, this response expresses the Division’s position on enforcement action only and does not express any legal conclusion on the question presented.
