- First 0.35 micron CMOS circuits completed in the
- France Telecom-CNET/ SGS-THOMSON Joint Center
-
- Crolles - July 13, 1995 - The joint center in Crolles, close to
- Grenoble, France, has completed the development of the 0.35
- micron CMOS process in accordance with the work schedule of this
- partnership between France Telecom-CNET and SGS-THOMSON
- Microelectronics, just one year after qualification of the 0.5
- micron process.
-
- The creation of the Joint Center in 1989 was agreed within the
- framework of the Jessi and Esprit Programs with the objective of
- carrying out the research and development necessary for the
- assembly of the 0.5 and 0.35 micron CMOS process.
-
- The two partners share equally the costs of research and
- development carried out in the clean room in Crolles, where the
- industrial manufacturing activities of SGS-THOMSON are also
- carried out as a natural progression to exploit commercially the
- research results. This perfect intellectual and geographical
- co-operation between research and industrial production has,
- since the creation of the Joint Center, proved to be extremely
- beneficial in terms of the rapidity with which the processes are
- introduced into the production line. Among those is the 0.5
- micron CMOS process, which is used to produce integrated circuits
- (ICs), such as MPEG decoder ICs, for which SGS-THOMSON is the
- world leader with more than two million devices sold to date, and
- the FFT8K for digital TV, recently introduced by CNET.
-
- The Joint Center uses equipment to process 200 mm silicon wafers
- and gathers together 125 researchers from both CNET and
- SGS-THOMSON.
-
- The 0.35 CMOS process, currently used in the assembly and
- development of a complex evaluation circuit of several million
- transistors, consists of five metal levels and involves more than
- 140 elementary operations. Among the features of particular
- interest in this technological process are selective tungsten
- vias, plasma inter-metal dielectric deposition, and
- chemical-mechanical planarization for the inter-metallic oxides.
-
- The critical elementary steps in the 0.35 micron CMOS process
- were previously developed within the Gressi partnership in
- Grenoble between CNET and LETI, the French microelectronics
- research institute, and validated in spring 1994. The transfer of
- know-how between Gressi and SGS-THOMSON was performed within the
- framework of an agreement finalized at the beginning of 1995.
- This was achieved within a very short time thanks to the perfect
- synergy and successful exchange of personnel between the Gressi
- teams in Meylan, the home of the France Telecom-CNET
- microelectronics research center, and LETI in Grenoble, and the
- Joint Center team in Crolles.
-
- As well as the evaluation circuit, the two partners are using
- complex circuit prototypes to further validate the process and
- accelerate the introduction of products based on this process.
- SGS-THOMSON is using a systolic processor as a test circuit for
- the estimation of movement in images. This circuit also makes it
- possible to test the latest CAD tools developed for complex
- circuits involving several million transistors and the associated
- design methodologies. Other circuits, particularly those
- connected with the computing and image processing markets, are in
- the design phase with a view to meeting the already existing
- market demands.
-
- As for the CNET, it is studying a programmable video processor
- for the coding of images, particularly in accordance with the
- MPEG-4 standard, currently undergoing standardization, as well as
- circuits for the terrestrial broadcasting of digital TV. This
- technology is now crucial to the introduction of new
- telecommunications services, and more particularly to the
- integration of highly complex source and channel coding
- algorithms.
-
- These results bear witness to the relevance of these Grenoble
- alliances to microelectronics and especially of the original
- collaboration represented by a research unit integrated into a
- production site. These partnerships are today the pride of the
- microelectronics sector in Europe and are fundamental to future
- programs.
-
- SGS-THOMSON is a global independent semiconductor supplier listed
- on the New York Stock Exchange (NYSE:STM) and on the Bourse de
- Paris. It designs, develops, manufactures and markets a broad
- range of semiconductor integrated circuits (ICs) and discrete
- devices used in a wide variety of microelectronics applications,
- including telecommunications systems, computer systems, consumer
- products, automotive products and industrial automation and
- control systems.
-
- France Telecom-CNET is the research organisation of France
- Telecom and the center in Meylan, near Grenoble is focused on
- silicon-based microelectronics. It has a high level of competence
- in the fields of software, electronics, telecommunications
- circuits, technologies and materials sciences.
