STMicroelectronics Unveils Design Platform for Low-Power Next-Generation 45nm CMOS

ST Confirms Early Availability of Design Platform for Power-Optimized System-on-Chip Solutions, Including 45nm Libraries and First Tape-Out of 45nm SoC Demonstrator IC

CROLLES, France, June 13 /PRNewswire-FirstCall/ -- STMicroelectronics (NYSE: STM), one of the world's leading semiconductor manufacturers, today unveiled details of its 45nm (0.045-micron) CMOS design platform for next- generation System-on-Chip (SoC) product development for low-power, wireless and portable consumer applications.

ST's innovative low-power process option with multiple threshold transistors cuts the silicon area by half compared to designs implemented in 65nm technology. At the same time, the process improves speed by up to 20% or reduces leakage current by half while in operation, and, in retention mode, reduces leakage current by several orders of magnitude. This latter option will bring important benefits to designers of portable products, where battery life is a significant factor.

The leading-edge 45nm low-power CMOS platform has already been used to complete, or tape-out, the design of a highly integrated 45nm demonstrator SoC device. This chip design includes an advanced dual-core CPU system and associated memory hierarchy, featuring the sophisticated low-power techniques required at the 45nm process technology node to combine new levels of performance with very low power consumption.

The new low-power design platform, which takes full advantage of the multiple features and modularity of 45nm process technology, was developed at the STMicroelectronics site in Crolles, near Grenoble, France, and verified at the 300mm wafer facility operated by the Crolles2 Alliance.

"Early access to low-power 45nm CMOS technology is crucial to industry- leading manufacturers in their development of new wireless and portable consumer products, especially for next-generation 3G and 4G handheld multimedia terminals," said Laurent Bosson, Executive Vice-President of Manufacturing and Technology R&D, STMicroelectronics. "The silicon developed using ST's low-power 45nm CMOS platform will enable applications to combine very high performance with low power consumption."

In common with other 45nm platforms being readied for deployment, ST's low-power 45nm process features all of the advanced modules required for high density and high performance. These important modules include: 193nm immersion lithography for critical patterning layers; shallow-trench isolation and transistor stressors; advanced junction engineering, using millisecond anneal; and very low-k inter-metal copper dielectric, allowing reduced interconnect capacitances. In addition two cell libraries are available: one optimized for high performance and the other for low power consumption, giving designers a rich selection of options.

The 45nm design platform is fully supported by the industry-leading CAD tools from Cadence, Mentor Graphics, Synopsys and Magma through design solutions that have been developed in partnership between ST and the respective EDA companies' individual R&D groups, allowing customers to immediately begin designing advanced SoC solutions using familiar industry- standard tools.

Further technical details of the full 45nm library and design platform, include:

    * Multiple library elements can be selected at the design level and used
      in the same design block, providing users of the platform with greater
      flexibility in optimizing performance and power consumption. This
      capability enables faster development of chips for use in high-
      performance and power-sensitive products.
    * Densities of up to 1600 Kgates per square mm are available, supporting a
      core supply of 1.1V, with metal pitches of 0.14-micron and from six to
      ten metal routing layers.
    * Power reduction techniques include adaptive vdd, low vdd operation,
      power shutdown, low standby current in retention mode, back bias and
      more.
    * Full range of 1.8V I/O cells.
    * Extremely dense embedded memories: single-port memories using six-
      transistor SRAM cells, with area sizes down to 0.25 square micron.
    * A fully compatible low-cost process variant for embedded DRAM with
      threefold density improvement versus SRAM is under development.
    * A broad portfolio of analog and radio-frequency IP (Intellectual
      Property) is under development to cover the need for a super-integrated
      single-chip system, while sophisticated digital IP modules such as
      microprocessors and DSPs will also be provided.

Additionally, the process has already recorded excellent results, including high-yield multi-Megabit SRAM test circuits, and fully functional SRAM test circuits operating at a supply voltage of 1.1V down to 0.9V.
