Keithley Partners with Stratosphere Solutions to Enable Advanced Process Characterization at Sub-65nm
Partnership delivers silicon-proven interoperable solution to drive parametric yields higher
Cleveland, Ohio - February 11, 2008
- Keithley Instruments, Inc. (NYSE:KEI), a leader in solutions for emerging measurement needs, announces a
partnership with Stratosphere Solutions, Inc. (Sunnyvale, CA), a provider of innovative parametric yield
improvement solutions for integrated circuit manufacturers. Keithley's partnership with Stratosphere Solutions
will address advanced process development and monitoring using an Array TEG (test element group) technology.
Parametric process variation at the sub-65nm level is posing significant challenges to design and test
engineers as IC manufacturers seek to produce ever-smaller devices. The semiconductor industry is seeing a rapidly
growing need for monitoring extremely sensitive production processes in order to optimize IC performance without
Keithley and Stratosphere Solutions will work together to provide mutual customers
with a unique characterization infrastructure that includes high volume, high throughput, and reliable parametric
measurements using Keithley's Series S600 Parametric Testers and StratoPro™ IP to ensure customer success.
"As semiconductor technology pushes the upper limits of device miniaturization to nano-scale levels,
measurement technology must not only keep pace but even lead manufacturers' ability to build and test these
devices," explained Mark Hoersten, Keithley vice president, business management. "As a leader in semiconductor
test technology, Keithley looks forward to collaborating with leading players in the industry to create innovative
solutions for the most advanced customer applications."
"We are excited to be working with Keithley to
deliver innovative, out-of-the-box, interoperable solutions that connect best-in-class tools, critical for our
industry." said Prashant Maniar, Chief Strategy Officer, Stratosphere Solutions, Inc. "As technology advances to
45nm and below, more and more customers face the challenge of ramping parametric yield. Our tightly integrated,
silicon-proven solution is a linchpin in empowering customers to drive parametric yield higher, reduce the cost of
ramping parametric yield, accelerate test time, and improve ROI."
Keithley's Series S600 Parametric
Testers help fabs and wafer foundries reduce their cost of test by being adaptable to changing device
technologies. Their ability to be repurposed as very minimal cost DC, RF, and array TEG testers provides capital
equipment reuse and therefore lowers the cost of test. The latest in the Series S600, the Model S680, combines, in
a single test system, parallel testing capability, high DC sensitivity, femtoamp-level resolution, and RF
s-parameter measurements up to 40GHz. This provides the industry's highest throughput and a lower cost of
ownership for measurements at the 65nm node and beyond.
Array TEG structures, like Stratosphere's award-winning StratoPro product suite, are increasingly becoming
mission-critical for characterizing semiconductor processes as geometries shrink below 65nm. Leading edge
semiconductor companies desire a de facto standard product, StratoPro, which delivers thousands of times higher
density for the same silicon area, highest resolution measurements, and improved overall test integrity.
StratoPro™, a Parametric ActiveMatrix™ silicon IP platform, empowers fab and fab-lite customers to characterize
with high accuracy, within-die statistics of electrical parameters and their variability. Customers choose the
65nm and 45nm silicon-proven StratoPro platform, because it provides 10 to 1000x greater test structure density,
performs very high resolution measurements, and, coupled with the Keithley tester platform, provides significant
improvement in test time. Fab customers use StratoPro™ during early process development, yield ramp, and
production monitoring. Fab-lite customers use the solution to characterize design-style dependent process
