eSilicon Achieves Significant Milestone by Booking Production Orders from More Than Fifty Customers

Orders Indicative of Company’s Growing Momentum

SUNNYVALE, Calif.-- May 22, 2008 -- eSilicon Corporation, a pioneering semiconductor value chain producer (VCP), today announced that it has achieved the significant milestone of having booked production orders from more than fifty customers in the current quarter. These orders cover devices in process technologies up to 90nm, addressing the communications, networking, storage, digital imaging, consumer and security markets. This achievement demonstrates the strong momentum achieved by the company, evident by the large number of customers who are actively buying production silicon.

“We are delighted and proud to have accomplished this important milestone,” said Jack Harding, chairman, president and CEO of eSilicon. “It establishes eSilicon’s position as a leading VCP and shows the size and diversity of our customer base. Shipping production silicon to more than fifty customers, in addition to the numerous customers who are engaged with us on the development of new products not yet in production, is a significant accomplishment for the company. I want to congratulate and thank all of our customers, suppliers and employees for their hard work and dedication in helping us achieve this milestone,” added Harding.

An important component of this milestone is the relationship that eSilicon has with TSMC, the world's largest dedicated semiconductor foundry. TSMC has played a critical role in enabling eSilicon to support its customers by providing access to leading-edge technology and production capacity.

“As a key supplier to eSilicon, we are pleased to help them reach this milestone,” said Rick Cassidy, President of North America, TSMC.

In today's competitive market, if a fabless company or a system OEM wants to succeed it must get a working chip to market as quickly as possible. This is not an easy process. At every phase of development there are substantial obstacles to overcome: chip complexity, multiple suppliers, integration challenges and time-to-market pressures. These challenges directly affect reliability, profitability and ultimately a company's success. eSilicon offers a comprehensive suite of services and a robust infrastructure that helps to overcome these obstacles so that its customers can be well positioned to meet the ever-increasing demands of their end markets. The value of the services provided by eSilicon to its customers is clearly evidenced by the increase in production orders over the past twelve months, ultimately enabling its customers a flexible, low-cost, lower-risk path to volume production of application specific integrated circuits (ASICs).
