EXHIBIT 99.1 TEGAL SIGNS DEFINITIVE AGREEMENT TO ACQUIRE SPUTTERED FILMS NAMES NEW CHIEF FINANCIAL OFFICER STRATEGIC ACTION TAKEN TO EXPAND CAPABILITIES IN PLASMA ENHANCED PHYSICAL VAPOR DEPOSITION TECHNOLOGY, ENHANCE DEPTH OF MANAGEMENT PETALUMA, Calif.--(BUSINESS WIRE)--Aug. 13, 2002-- Tegal Corporation (Nasdaq:TGAL - News), a leading designer and manufacturer of plasma etch systems used in the production of integrated circuits for wireless, opto-telecom and other advanced technology applications, today announced the signing of a definitive agreement to acquire Sputtered Films, Inc., a privately held, leading manufacturer of high-performance sputtering equipment for thin film deposition. The acquisition, for 1.5 million shares of Tegal's common stock plus a performance-based future cash earnout, is expected to be completed during August 2002. Tegal also announced the appointment of Thomas R. Mika, 51, as executive vice president and chief financial officer. Mika, who has served on Tegal's board of directors since 1992, has resigned from the board to assume his new position. Sputtered Films, with headquarters in Santa Barbara, California, is a leader in the design and manufacture of sputtering equipment for semiconductor, photomask, advanced packaging (including flip chip) and compound semiconductor applications. The late Peter Clarke, the inventor of the world's first magnetron sputtering device, founded Sputtered Films more than 35 years ago. The company recorded revenues of approximately $5 million over the past 12 months, and has approximately 18 employees, who will continue to be based in Santa Barbara. The acquisition will include Sputtered Films' patented Endeavor(TM) product lines, which are used to deposit some of the industry's most critical thin films. Carole Anne Clarke Demachkie, daughter of the founder, will be named a Tegal vice president and general manager of the subsidiary, reporting to Michael Parodi, president and chief executive officer of Tegal. Demachkie has been actively involved with Sputtered Films since 1995 and is currently part of its senior management team. "With Sputtered Films, Tegal gains important, complementary product lines to better serve an expanded customer base," said Parodi. "The acquisition builds revenues and will have a positive impact on gross margins. Tegal's industry leading capabilities in new materials etch will be complemented by Sputtered Films' advanced deposition solutions. Additionally, we look to accelerate sales and service for the Endeavor product lines through our award-winning support team and international sales force. Both companies are highly regarded by their customers and, by working together as a unified team, we can build on our respective strengths while taking advantage of the economies offered by a business combination." Demachkie added, "Our union with Tegal is clearly an important step for Sputtered Films. I am pleased that through Tegal we will continue Sputtered Films' legacy of technology leadership for our valued customers." On completion of the acquisition, Tegal estimates its worldwide employee count will remain at approximately 140, its level prior to the acquisition. Independently, Tegal recently reduced its operating expenses by an amount roughly equal to that of the Sputtered Films operation. Mika, Tegal's new chief financial officer, filling a post that has been occupied on an acting basis by the corporate controller, has more than 25 years of senior management, finance and consulting experience. During his career, he has been the managing director of International Management Technology Corporation (IMTEC), a private investment firm active in the management of several companies; former president of Soupmasters International, Inc.; managing director of Disc International, Inc., a software firm; managing consultant with Cresap, McCormick & Paget; and policy analyst for the National Science Foundation. He holds a Master of Business Administration degree from the Harvard School of Business and is a graduate of the University of Illinois at Urbana-Champaign. "We are delighted to have Tom Mika join Tegal as an officer of the company," Parodi said. "His appointment brings important management depth to our company as we work toward implementing our strategy to maximize new opportunities as the semiconductor industry continues to move toward recovery."
