Applied Materials Introduces New High-Performance Gas Chemistry for Critical Etch Applications
SANTA CLARA, Calif.--(BUSINESS WIRE)--Sept. 28, 1999--
New C4F6 Chemistry Developed With Ausimont Delivers Technology and
Environmental Advantages
Applied Materials, Inc., in collaboration with Ausimont, a company of the Montedison Group and a leading provider of fluorine chemistry, introduces Sifren(R) 46, a new environmentally friendly, high-performance C4F6, etch chemistry for its Dielectric Etch IPS(TM) Centura(R) and Dielectric Etch Super e(TM) Centura systems. The new Sifren(R) 46 provides higher etch rates, better profile control and higher selectivity to photoresist in critical dielectric etch applications. Several patents have been filed by Applied Materials regarding the use of Sifren 46 which is now available to customers through major gas distributors.
"Sifren 46 gas improves dielectric etch process results in key
areas such as copper dual damascene, self-aligned contact and high
aspect ratio contact etch applications, including low K materials,"
said Gerald Yin, vice president of Applied Materials' Etch Group. "It
also exhibits significant environmental benefits over current etch
chemistries, which is an important issue for our customers. We are
currently testing Sifren 46 with several customers to etch a variety
of devices and have demonstrated significant advantages on small
features. Chipmakers using our dielectric etch systems can benefit
from these advanced process capabilities as they move their designs to
0.15 micron and beyond."
The semiconductor industry has been investigating new gas
chemistries in an effort to reduce global warming emissions. In
addition to improving etch process performance, C4F6 gas features low
global warming emissions and zero ozone depletion potential.
Massimo Malavasi, vice president of Ausimont's Research &
Development, said, "Working with Applied Materials on this new
chemistry gives us the opportunity to team with the largest etch
company in the world on an exciting innovation in semiconductor
processing. As we expand our presence in the semiconductor industry,
we are happy to have Applied Materials as a technology partner in
finding new solutions to improve customers' environmental safety and
process results."
According to Dataquest, a market research firm, equipment for
dielectric etching is the largest and fastest growing etch market
segment, totaling $954 million in 1998 and projected to grow to $2.2
billion by 2003. Dielectric etching is one of the key technologies
involved in the transition to copper-based semiconductor chips.
