10/27/2004 - Texas Instruments Incorporated (TI) (NYSE: TXN) announced qualification of its advanced 90 nanometer (nm) copper process on 300 millimeter (mm) copper wafers in its DMOS6 facility. By expanding its 300-mm manufacturing to include the proven 90-nm CMOS process, TI gives customers access to the many advantages that come with high volume manufacturing at the most advanced technology node. Smaller, more highly integrated, lower power products, along with the manufacturing cost advantage that comes with 300-mm will result from this qualification.
Migrating the 90-nm process to 300-mm wafers allows TI to deliver up to 2.4 times more die per wafer over 200-mm, and reduces production costs 30 - 40 percent. The first products to result from the qualified 90-nm, 300-mm process include wireless baseband processors for advanced mobile handset devices.
“TI remains at the forefront of bringing the most advanced semiconductor manufacturing technologies to volume production,” said Kevin Ritchie, senior vice president of Texas Instruments and director of worldwide manufacturing. “As one of the first to qualify 90-nm process technology on 300-mm wafers, TI is continuing its commitment to bring our customers products with market-leading performance, power consumption, integration and cost.”
Continuing 90-nm Momentum
TI delivered its first 90-nm device in January 2003 from its 200-mm KFAB facility, positioning the company among the first semiconductor companies to deliver working 90-nm products. Today, TI has nearly 20 different products based on the 90-nm process in various stages of production.
“By continuing its technology investments, TI maintains its ability to own its technology roadmap and manufacture cost-effective, differentiated products in volume production,” said Dan Hutcheson, president of market research firm VLSI Research. “Fully qualifying its 90-nm process for 300-mm production strengthens TI’s position among the few companies remaining that can provide advanced chip manufacturing capabilities.”
With the ability to pack over 400 million transistors on a single chip, TI’s 90-nm process drives cost-effective, system-on-a-chip (SoC) solutions with the highest levels of performance and power savings. The 90-nm process features transistor gates as small as 37-nm with nine layers of copper metal and its advanced integration capability supports a wide range of analog and RF components, including the advanced Digital Radio Processor (DRP) architecture. The process delivers a 50 percent improvement in transistor performance over its fastest 130-nm transistor.
TI’s 90-nm process uses a collection of transistors that are “tuned” for different functions on-chip to meet a variety of performance, density and power consumption requirements. This is accomplished through adjustments to the transistors’ gate length, threshold voltage, gate oxide thickness or bias conditions. The result is that transistors with the highest performance can be used for critical functions such as signal processing, while transistors with lower power consumption can be used to support functions with lower active performance requirements. TI leverages this approach across several optimized 90-nm process flows that address a variety of end products and applications. Sun Microsystems, for example, is expected to leverage the availability of the 90-nm process on 300-mm wafers for its UltraSPARC® microprocessors.
Advanced 300-mm Manufacturing
Located in Dallas, Texas, TI’s DMOS6 facility is the company’s most advanced production facility with over 150,000 square feet of clean room space and is leading the way for TI’s transition of its process technology development to 300-mm wafers.
In July 2002, DMOS6 became one of the first 300-mm facilities in the world to enter customer-qualified production on 130-nm copper wafers and will have a combined output of 14,000 wafers per month by the end of 2004. DMOS6 is capable of producing 30,000 wafers per month when fully utilized as demand for its advanced products continues.
TI also announced its strategy to further expand 300-mm manufacturing with ground breaking of its second 300-mm facility in mid-November. The new facility in Richardson, Texas, is slated for 65-nm production. The planned site includes a clean room of over 220,000 square feet at the center of over a million square feet of office, manufacturing and support space. Once complete, TI’s new fab will produce a wide range of digital signal processing (DSP) and analog-based SoC devices for wireless, broadband and digital consumer applications.
