FOR IMMEDIATE RELEASE                                             July 8th, 2004

Mentor Graphics Offers Technology Design Kit and Design Flow for SMIC
0.18-micron Mixed-Signal Process

Shanghai, China, July 8th, 2004 - Mentor Graphics Corporation (Nasdaq: MENT) and
Semiconductor Manufacturing International Corporation, (SMIC; NYSE: SMI, HKEx:
0981) today announced the availability of a Technology Design Kit (TDK) for
SMIC's 0.18Um mixed-signal process technology. The open-source design kit, built
for use with the Mentor Graphics(R) Analog/Mixed-Signal (AMS) IC Design Flow,
enables IC design companies to rapidly set up all aspects of their design
environment - including schematic entry, simulation, layout, verification and
parasitic extraction - using the SMIC 0.18Um process technology.

     "Setting up a mixed-signal design environment is often time- and
labor-intensive," said Jue-Hsien Chern, vice president and general manager, Deep
Submicron (DSM) division, Mentor Graphics. "Mentor is committed to offering
customers TDKs to simplify and accelerate this process, so we are pleased to be
working with SMIC to support its mainstream 0.18Um process technology."

     "Our 0.18Um process, together with Mentor's best-in-class mixed-signal IC
design flow, can meet the most stringent design and manufacturing requirements
of our customers," said Paul Ouyang, Fellow of Design Services Division, SMIC.
"With this design kit, our customers can enjoy improved predictability and
productivity of their designs with a rapid and confident path to silicon
success."

Customer-Proven Kit

     SMIC's customers who have benefited from this design kit include
Pixelworks, a leading provider of system-on-chip ICs for the advanced display
market. "The Mentor/SMIC TDK helped us realize critical time savings, enabling
us to meet our goals for getting to market rapidly," said Mike West, vice
president and Fellow at Pixelworks. "We were able to ramp up a new design start
in a fraction of the time using this TDK. In addition, foundry-qualified
parameterized device generators in the TDK, along with IC Station's LDL
(Logic-Driven Layout) Cockpit, facilitated easy and relatively painless
migration of our designs from an earlier process technology to the new SMIC
0.18Um process."

     The new design kit includes the SMIC-supported EldoTM analog simulation
models and Calibre(R) DRC, LVS and extraction technology files. They also
include schematic symbols for the Design Architect(R)-IC tool, programmable
device generators for schematic-driven layout with IC Station(R), process
definition files, and all other configuration files necessary for the effective
utilization of the Mentor Graphics complete AMS IC design flow.

Availability

     The TDK has been validated and is now available for use with the Mentor
Graphics AMS IC Design Flow. To access this release, visit the Mentor Web site
or contact SMIC at Design_Services@smics.com.

Mentor Graphics Integrated AMS SoC Design Tools

     Mentor Graphics delivers superior technology for AMS SoC design, from
capture and simulation through physical implementation, verification and
analysis. The tool suite includes the Design Architect-IC schematic entry
product with a powerful AMS SoC design cockpit, and the IC Station custom layout
product with its integrated ICassemble solution for automated routing and chip
assembly. The ADVance MSTM tool is a single-kernel, language-independent
simulation environment for digital, analog, mixed-signal and RF circuits. The
Calibre and Calibre xRCTM tools deliver the industry's highest capacity,
performance and accuracy for physical verification and parasitic
