Systems Built on Its Unity Platform

Mar 15, 2006, 00:00 ET from Ultratech, Inc.

    SAN JOSE, Calif., March 15 /PRNewswire-FirstCall/ -- Ultratech, Inc.
 (Nasdaq:   UTEK), a leading supplier of lithography and laser-processing systems
 used to manufacture semiconductors and nanotechnology devices, today announced
 that Siliconware Precision Industries Co. Ltd. (SPIL), one of the world's
 leading semiconductor foundries, has ordered several Ultratech Unity AP200
 advanced-packaging (AP) lithography systems.  Slated for 200-mm devices, the
 tools will be delivered to SPIL's Taiwan headquarters over the next few
 quarters.  The AP200 is built on Ultratech's customizable Unity Platform(TM),
 which provides the cost of ownership (CoO), operational flexibility, technical
 abilities and technology extendibility that are essential for foundries to
 stay on their aggressive technology roadmaps.
     According to Jan Vardaman, president and founder of TechSearch
 International, Inc., the solder bump market is positioned for strong growth
 over the next several years, with an expected compound annual growth rate of
 approximately 30 percent.  This growth is mainly driven by high-end logic and
 communications devices.
     Johnson Tai, SPIL vice president, Manufacturing 3rd Division, noted, "To
 meet the rise in demand for communications chips, SPIL is on an aggressive
 bump-capacity expansion plan.  We chose Ultratech's Unity-based AP200 because
 it provides the technology, flexibility, reliability and extendibility needed
 to meet both our current and future productivity and technology requirements."
     "Ultratech's AP systems are becoming the advanced-packaging lithography
 industry standard," said Manish Ranjan, director, product marketing at
 Ultratech.  "The surge in solder-bump applications is a significant catalyst
 behind the growing demand for our AP tools.  This order signals the success of
 the Unity Platform's adoption with device manufacturers, as well as in the
 growing foundry market, where requirements are primarily driven by economic
 factors.  We greatly value our strong relationship with SPIL and will continue
 to develop technology to support their next-generation AP requirements."

 lithography technologies and applications; integration, development and
 associated expenses of the laser processing operation; delays, deferrals and
 cancellations of orders by customers; cyclicality in the semiconductor and
 nanotechnology industries; pricing pressures and product discounts; high
 degree of industry competition; intellectual property matters; expiration of
 licensing arrangements, and the resulting adverse impact on our licensing
 revenues; changes to financial accounting standards; changes in pricing by us,
 our competitors or suppliers; customer concentration; international sales;
 timing of new product announcements and releases by us or our competitors;
 ability to volume produce systems and meet customer requirements; sole or
 limited sources of supply; ability and resulting costs to attract or retain
 sufficient personnel to achieve our targets for a particular period; dilutive
 effect of employee stock option grants on net income per share, which is
 largely dependent upon us achieving and maintaining profitability and the
 market price of our stock; mix of products sold; rapid technological change
 and the importance of timely product introductions; outcome of litigation;
 manufacturing variances and production levels; timing and degree of success of
 technologies licensed to outside parties; product concentration and lack of
 product revenue diversification; inventory obsolescence; asset impairment;
 effects of certain anti-takeover provisions; future acquisitions; volatility
