Texas Instruments announced late in October 2004 that it had qualified
its advanced 90nm copper process on 300mm wafers in its DMOS6 facility.
The result of the migration of the 90nm process to 300mm wafers allows
TI to deliver up to 2.4 times more die per wafer over 200mm, and
reduces production costs 30 - 40 percent. The first products to result
from the qualified 90nm, 300mm 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 90nm
process technology on 300mm wafers, TI is continuing its commitment to
bring our customers products with market- leading performance, power
consumption, integration and cost."
The 90nm process features transistor gates as small as 37nm with nine
layers of copper metal and its advanced integration capability supports
a wide range of analog and RF components, including Digital Radio
Processor (DRP) architecture. The process delivers a 50 percent
improvement in transistor performance over its fastest 130nm
transistor, according to the company
TI's 90nm 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 delivered its first 90nm device in January 2003 from its 200mm KFAB
facility, and has nearly 20 different products based on the 90nm
process in various stages of production.
