Today KLA-Tencor Corporation (NASDAQ:KLAC), the world’s leading supplier
of process control and yield management solutions for the semiconductor
and related industries, announced XP, a new upgrade package for 28xx
broadband brightfield inspection systems. The XP package is the first
commercially available product to give an inspection system access to
standard IC design layout files — the instructions that enable mask
shops to pattern the mask. With access to this information, the
inspection system can use knowledge of the defect’s location within the
circuit to better estimate its probability of affecting device yield. In
addition, XP can use the results of the design-aware wafer inspection to
identify features on the mask that may be particularly sensitive to
process variations during printing. These and other features of the XP
upgrade package are designed to improve the sensitivity and productivity
of existing 28xx inspectors and raise the information content of defect
results, helping to accelerate identification and resolution of defect
issues.
“As chip complexity and price pressure increase in our consumer-driven
markets, our customers are asking for tools to facilitate root-cause
defect analysis, improve their productivity, and effect faster, more
efficient ramps,” remarked Mike Kirk, Ph.D., vice president and general
manager of KLA-Tencor’s Wafer Inspection Group. “Today our leading-edge
fabs have to cope with advanced lithography techniques that enable 193nm
lithography to print features with dimensions nearly one-tenth the
illumination wavelength, dimensions that can now be measured in
countable atoms. In this environment, even the smallest defect on a
wafer or marginal pattern on a mask can have an enormous yield impact.
Our new XP package represents a major step forward in addressing our
customers’ need to optimize defect capture and identify systematic and
other yield-relevant defects from a sea of irrelevant or ‘nuisance’
defects.
