Chartered Expands Foundry Market Access to IBM's 90nm SOI Technology

Licensing agreement with IBM enables Chartered to extend 90nm SOI market availability

MILPITAS, Calif. and SINGAPORE - April 20, 2006 - Chartered Semiconductor Manufacturing (Nasdaq: CHRT and SGX-ST: Chartered), one of the world's top dedicated semiconductor foundries, announced today that it has licensed the 90-nanometer (nm) Silicon-on-Insulator* (SOI) technology from IBM. The agreement enables Chartered to expand the use of the technology to areas such as consumer, multi-media, communications, automotive and industrial applications, thereby delivering more choice and flexibility to foundry customers for manufacturing their leading-edge products. The SOI technology is production-proven, having been used in a range of high-volume applications such as consumer-market games and enterprise information solutions, and demonstrated extremely low defect densities.

"The licensing agreement allows us to open new markets for SOI technology and continue to reap the benefits of a common platform approach. It positions us to better serve the increasingly demanding power and performance requirements of a variety of products, as well as expand our market reach and client base," said Kevin Meyer, vice president of worldwide marketing and platform alliances at Chartered. "We intend to expand our collaboration with our value-chain partnerships to develop a comprehensive ecosystem in support of our portfolio of leading-edge technologies to help mitigate the challenges and risks of design and manufacturing."

The agreement follows an initial outsourcing arrangement between the two companies announced in January 2004. Under that agreement, Chartered successfully implemented the breakthrough IBM 90nm technology in its Singapore-based Fab 7 and manufactured CPU products for Microsoft Corporation's popular Xbox 360 game console.

"As advanced process technology for semiconductors expands from primarily performance-driven applications to performance and low power, SOI technology is becoming an increasingly critical capability for foundries to offer. Over the next five years, Semico projects SOI wafer production to increase at a CAGR of over 40 percent," said Joanne Itow, Managing Director at Semico Research Corporation. "The IBM SOI technology has been production-proven on its own enterprise-server products, as well as in volume consumer products such as those produced for Microsoft's Xbox line. That experience, combined with the successful track record of technology transfer and cooperation between IBM and Chartered in other areas, makes this an excellent fit for Chartered and expands the opportunity for more companies to leverage the benefits of SOI."

Chartered today also announced an agreement at 65nm, which allows Chartered to utilize the IBM SOI technology to manufacture Microsoft's CPU products at 65nm.

"Today's agreement with Chartered is a significant step forward in driving adoption of IBM process technology around the world," said Walter Lange, field executive, IBM Systems and Technology Group. "Along with the innovative Common Platform strategy, IBM and Chartered continue to re-define the traditional semiconductor supply chain model."

* SOI refers to placing a thin layer of silicon on top of an insulator, such as silicon oxide or glass. The transistors (switches that are used in microprocessors) are then built on top of this thin layer of SOI. The basic idea is that the SOI layer reduces the capacitance of the switch, so it operates faster.
