Applied Materials Takes CMP Process Control to 45nm and Beyond With
FullVision Endpoint System
SANTA CLARA, Calif.--(BUSINESS WIRE)--Applied Materials, Inc. today announced its new Applied FullVision™
system that enables real-time control of dielectric CMP1
processes to the 45 nanometer (nm) device node and beyond. The
FullVision system couples Applied’s patented
window-in-pad technology with multiple-wavelength spectroscopy to
deliver advanced in situ endpoint capability for a variety of dielectric
materials, including oxide, STI2, and poly CMP
applications. The system demonstrates high repeatability across all
applications with less than 150 angstrom, 3-sigma endpoint accuracy on
patterned wafers. A major advance over single wavelength endpoint
technologies, the FullVision system offers improved measurement accuracy
with 50% higher reliability for dielectric applications.
“CMP endpoint technology was pioneered by
Applied Materials and is key to delivering benchmark CMP performance,”
said Dr. Hichem M’Saad, vice president and
general manager of Applied Materials’
Dielectric Systems and CMP Business Group. “As
films become thinner, CMP becomes increasingly difficult, requiring much
more precise wafer-to-wafer process control to achieve acceptable
yields. Using broadband spectral analysis, FullVision technology
monitors individual polishing zones across the wafer to provide twice
the accuracy and repeatability of competitive systems on a wide variety
of process steps – without compromising
throughput. These are vital requirements for advanced device
manufacturing.”
The FullVision system has already been adopted by major memory customers
on their Applied Reflexion®
LK CMP systems in high volume manufacturing. For these customers, the
system has enabled higher CMP yield by significantly reducing wafer
scrap caused by drifts in consumable sets and incoming wafer profile
variations.
Applied Materials leads the industry in CMP technology —
with an installed base of more than 900 300mm CMP systems worldwide —
and in providing advanced in situ metrology for ensuring best-of-breed
planarization performance. See http://appliedmaterials.com/products/reflexion_lk_cmp_4.html
