Chipnuts and SMIC to Jointly Offer C626 Multimedia Chip For Mobile Phones

SHANGHAI, China -- May 16, 2006 -- Chipnuts Technology (Shanghai), Inc. ("Chipnuts") and Semiconductor Manufacturing International Corporation ("SMIC", NYSE: SMI; HKSE: 0981.HK), one of the leading foundries in the world, jointly announced today that Chipnuts' C626 chip, a multimedia chip for mobile phones, has successfully entered commercial production at SMIC.

Manufactured using SMIC's 0.18um mixed-signal process technology, C626 is the newest addition to Chipnuts' line of mobile multimedia System-on-Chip (SoC) co-processors. The C626 chip is optimized for low power consumption and high performance, providing key features such as MPEG-4 decoder and analog codec for video and audio playback and recording. The chip also included Chipnuts' proprietary and unique MINI-MTVTM feature enabling true mobile Karaoke. In addition, the C626 chip can play mp3 files in the background while simultaneously supporting capture and review of pictures on mobile phones.

SMIC provided customized Device Under Pad I/O design services for the C626 chip, which allowed for a small die size while increasing system design flexibility.

"Chipnuts has had a long-standing collaboration with SMIC dating back to Chipnuts' establishment. During pilot production, we were highly impressed with SMIC's comprehensive support and services," said Mr. John Yu, Chief Operating Officer of Chipnuts, "As our business continues to expand, our collaboration with SMIC will also continue to strengthen."

"SMIC is honored to provide foundry services to Chipnuts, whose rapid development exemplifies the overall growth of China's fabless design industry. SMIC's manufacturing expertise coupled with Chipnuts' design successes will further elevate the mobile phone applications chip market," said Mr. Ning Hsieh, vice-president of marketing and sales at SMIC.

At a press conference held today, Chipnuts and SMIC signed a Memorandum of Understanding that serves to strengthen the companies' business relationship going forward.
