X-FAB and 1st Silicon to Merge

Erfurt, Germany, Sarawak, Malaysia, 三月 22, 2006.

XTRION N.V., the controlling shareholder of X-FAB Semiconductor Foundries AG, one of the world's leading analog mixed-signal semiconductor foundries, and Sarawak Economic Development Corporation, the controlling shareholder of 1st Silicon (Malaysia) Sdn. Bhd., a premier dedicated global semiconductor foundry, have agreed to merge both companies. The move, which signals X-FAB's continuing growth and nearly doubles its capacities, extends X-FAB's business activities to the Asia/Pacific region and gives it access to first-class manufacturing capabilities for 0.25, 0.18 and 0.13 micron technologies.

The combined manufacturing capacity of the merged company will be approximately 700,000 200mm-equivalent wafers per year, and the sales of the new company are expected to exceed $300 million USD in 2006.

Commenting on the merger, X-FAB's Chairman of the Supervisory Board, Mr. Roland Duchâtelet, said, "The synergy gained by integrating 1st Silicon into X-FAB reflects excellent value for customers, fabless companies and IDMs alike. They will see no change in the long-term strategy and no change in support for existing customers. Moreover, the industry will experience the same expert precision and reliable, cost-effective manufacturing of high-quality products that both companies are known for."

YAB Pehin Sri Haji Abdul Taib Mahmud, Chief Minister of Sarawak, who called the merger a "win/win" for both companies, said, "Becoming part of a company as healthy and forward-looking as X-FAB is the ideal business move for 1st Silicon. It provides the best ROI, and creates long-term stability for a Malaysian-based manufacturing site for high-performance technologies."

Hans-Juergen Straub, Chairman and CEO of X-FAB, added, "1st Silicon, with its advanced processes, provides an excellent complement to X-FAB's current wafer production capabilities, and opens our analog/mixed-signal roadmap to new technology platforms and application areas. We are pleased to extend our local manufacturing presence to Asia."
