KLA-Tencor Announces Two Additions to Litho/Etch Process Control Portfolio

  KLA-Tencor Announces Two Additions to Litho/Etch Process Control Portfolio

New metrology and inspection tools facilitate advanced patterning techniques
for manufacturing sub-20nm memory and microprocessor chips

MILPITAS, Calif., Feb. 25, 2013

MILPITAS, Calif., Feb. 25, 2013 /PRNewswire/ -- At the SPIE Advanced
Lithography conference, KLA-Tencor Corporation (NASDAQ: KLAC) announced its
SpectraShape™ 9000 optical critical dimension (CD) metrology system and
BDR300™ backside defect inspection and review module. The SpectraShape 9000 is
a new metrology system capable of monitoring the shapes of three-dimensional
transistors, memory cells and other key structures that enable
high-performance memory and microprocessor chips. The BDR300 inspects and
reviews the back side of the wafer for defects that can cause patterning
problems on the wafer's front side. The two new systems are designed to enable
volume production of integrated circuits at sub-20nm design rules.

"In this era of highly extended 193nm immersion lithography, our customers are
innovating on several fronts to deal with process tolerances in lithography
and etch that have become remarkably tight," said Brian Trafas, Ph.D., chief
marketing officer at KLA-Tencor. "The two products we have launched today
tackle two key process control issues in this area: scanner focus-related
defects and failure or underperformance of finFETs, vertically stacked NANDs,
and other three-dimensional structures, caused by small deviations in shape.
The BDR300 and SpectraShape 9000 are designed to help our customers navigate
the monumental challenges they are facing today in lithography and etch."

The new SpectraShape 9000 introduces a laser-driven plasma light source and
several other significant advances that enable leading-edge dimensional
metrology capability for a broad range of materials and structures. The
SpectraShape 9000 features higher sensitivity and throughput than its
predecessor in order to accommodate the industry's need for tighter process
control at sub-20nm nodes—a need to measure more sites per wafer on an
increasing number of layers. It also supports innovative metrology targets
designed for multiple-patterning lithography.

The new BDR300 back-side inspection and review module for the CIRCL™ cluster
tool features a dramatic improvement in defect sensitivity over that of its
predecessor, allowing fabs to find and classify sub-micron back-side defects,
which can agglomerate and affect yield at advanced nodes. The CIRCL cluster is
now available as a stand-alone back-side inspection and review system, a
configuration designed to support an increasing industry requirement to
inspect the back sides of wafers before wafers enter the scanner. Clean wafer
back sides reduce the probability of contaminating the scanner chuck and
affecting subsequent product.

Multiple SpectraShape 9000 shape metrology systems have been installed at
leading logic and memory chip manufacturers, where they are replacing existing
CD/shape metrology tools for new technology development and ramp or fulfilling
requirements for additional metrology capacity. The first CIRCL tools
containing the BDR300 module have also been installed and are being used for
proactive scanner monitoring as well as traditional after-develop defect
inspection. To maintain the high performance and productivity demanded by
leading-edge production, the SpectraShape and CIRCL tools are backed by
KLA-Tencor's global, comprehensive service network.

SpectraShape product web page. For more information on the BDR300 module or
