Exhibit 99.1

ASM International N.V.

ASM International N.V. and Shareholders

Request Three Month Extension from Enterprise Court

BILTHOVEN, The Netherlands – September 4, 2008 — ASM International N.V. (NASDAQ: ASMI and Euronext Amsterdam: ASM) in consultation with Hermes and Fursa today submitted a request to the Enterprise Court to suspend the enquiry hearing initially scheduled for September 15, 2008 for a three-month period, that is, until approximately December 15, 2008. This request implies that the EGM initially scheduled for October 22, 2008 will be postponed until approximately January 22, 2009.

The reason for the suspension request is that the Transaction Committee has not finalized its assignment to assist ASMI to explore and consider its position and options following the unsolicited indicative offer of June 17, 2008 from Applied Materials (AMAT) and Francisco Partners (FP) to acquire all of ASMI’s front-end business. This offer was rejected by ASMI for the reasons set forth in the press release of June 20, 2008. Subsequently, ASMI has clarified a number of questions and issues raised by AMAT and FP. ASMI is awaiting presently whether a further offer from AMAT and/or FP will be forthcoming.

It is expected that the Enterprise Court will rule on the extension request within the next few days.

Further announcements will be made if and when appropriate.
