Fujitsu Develops 90nm CMOS Technology for Digital Consumer and Mobile Applications

(PRWEB) July 30, 2003

Fujitsu recently announced that is has developed and begun accepting orders for the CS101 Series of system-on-chips (SoCs) employing its state-of-the-art 90nm CMOS technology.


Fujitsu was among the first in the industry to deploy 90nm CMOS technology, starting production at its Akiruno Technology Centre in December 2002. The company first used the technology in its own high-end products that demanded ultra-high speed performance. The new SoC platform builds on the expertise developed at the Akiruno Technology Centre in 10-layer copper interconnects, Low-k insulating material, and other advanced technologies, making increased integration and reduced power consumption available for the SoC chips for digital consumer and mobile applications.


The CS101 Series achieves roughly double the level of integration of the company’s existing CS91 Series of SoCs: up to 100 million gates, with the lowest power consumption in the industry, and a leakage current one-tenth that of the CS91 Series. All these features make the new lineup especially well suited to mobile devices for which compactness and low power consumption are especially important.


With the adoption of Fujitsu’s new SoC device, a mobile phone could offer six consecutive hours of talk-time and up to 1,000 hours of standby time, and a credit card-sized digital camera could be miniaturised even further.


Fujitsu has a strong production track record in advanced process technologies combining copper interconnects and Low-k insulating material for its last two generations of system devices, 0.13¬Ķm and 90nm. Based on this proven record of reliability, Fujitsu is now making these technologies available to implement in SoC chips for digital consumer and mobile applications.


In addition to offering increased integration and functionality, Fujitsu can help customers cope with the problem of long, complex design cycles with its DesignExpress¬ô short TAT service, which can halve the time and steps required in design.


Fujitsu plans to extend the CS101 series with the addition of a high-speed interface for use in networking equipment, and will roll out products for an expanded range of applications starting next year.


Main Product Features


1. Low Power-Consumption Transistor Technology


Leakage current of the transistor is held to the lowest levels in the industry, cutting standby power consumption to roughly one-tenth that found in the company’s existing devices, the CS91 Series. When running at 1.2V, operating power consumption is 2.7nW (at 1 gate, 1MHz), roughly half that of earlier devices.


2. Advanced Process Technology for Increased Integration


With a density of 420,000 gates per square millimetre, this design can accommodate up to 100 million gates per chip, roughly double that of its predecessor. Each SRAM cell uses only 1.14 ¬Ķm2, among the smallest in the industry. Copper interconnects¬óup to ten layers of them¬óminimise resistance, and the use of Low-k insulating material across the entire chip for reduced interconnect capacitance helps to minimise the impact on electrical characteristics.


3. Optimised Design with Three Types of Transistors Achieves Both Low Power Consumption and High Speed


Adopting a mixture of three different kinds of core transistors¬ólow leakage current transistors, high-speed transistors, and ultra-high-speed transistors¬óenables the SoCs to achieve the twin goals of low power consumption and high speed. The gate delay time, which uses the high-speed transistors, is 12pS, about 70% faster than the CS91 Series of products.


4. IP Macros for a Wide Range of Features


To support a wide range of applications, which may require A/D and D/A converters, PLLs, high-speed interfaces, low power consumption or high speeds, Fujitsu offers a range of fine-tuned macros.


5. Design Environment for Faster, Simpler Design Processes


Fujitsu provides physical prototyping for this platform. By introducing this methodology, customers can reduce design time significantly. And with Fujitsu’s short TAT service DesignExpress, customers can design FPGAs and ASICs concurrently, reducing design time and steps in half.
