PDF Solutions(r) and TIBCO Spotfire(r) Strategic Alliance Unveils dataPOWER(r)
VSF for Visual, Interactive Yield Management

SAN JOSE, Calif., June 30, 2009 (GLOBE NEWSWIRE) -- PDF Solutions, Inc.
(Nasdaq:PDFS), the leading provider of yield improvement technologies and
services for the IC manufacturing process life cycle, today introduced an
innovative yield management solution called dataPOWER(r) VSF. The result of a
strategic alliance with TIBCO Software Inc., dataPOWER(r) VSF is designed to
provide a new, higher degree of intuitive and powerful yield analysis and
visualization capabilities to the semiconductor and photovoltaic industries.

dataPOWER(r) VSF brings a striking degree of visual interactivity to the
analysis of high volume, complex semiconductor data. This interactivity allows
users to more rapidly gain insight into the outliers, trends and relationships
that determine the performance, quality and speed-to-market of cutting edge
semiconductor products. Questions of the data can be asked and answered in rapid
visual strokes, using intuitive dynamic filtering, live aggregation, on-the-fly
hierarchies, custom KPIs and visual drill-down.

dataPOWER(r) VSF is a highly-optimized query interface to PDF's dataPOWER
database, custom-developed, semiconductor-specific visualizations and native
Spotfire(r) visualizations that enable semiconductor customers to perform
rapid-fire "what if" analysis of their manufacturing data. dataPOWER(r) VSF
ships with pre-defined templates that will help users get started quickly. These
can be extended, or new ones created instantly via "drag and drop" so that any
data investigator, not just power users, can get to root cause quickly and
confidently. dataPOWER(r) VSF has been designed to provide users unparalleled
ease-of-use for interactive visual analysis of sort, test, bin, parametric,
defect, metrology, wafer, lot and equipment history, plus process fault
classification and other custom data classes in the dataPOWER(r) database.

"The most demanding technical experts in the semiconductor design and
manufacturing world have a history of choosing PDF Solutions' products. With the
release of dataPOWER(r) VSF, we now make it possible to extend a high degree of
analytical power to a much broader audience of technical and managerial users,"
stated David Joseph, PDF Solutions' Chief Strategy Officer. "This concept of
deploying highly application-specific capabilities on an easy-to-use, enterprise
analytics platform is a first for the industry. We believe our customers will
benefit greatly because, while select experts can be significantly more
efficient, newly empowered casual users can exponentially increase the decision
making power of the organization as a whole."

"We are pleased to have an industry leader such as PDF Solutions as a partner in
high tech yield management," commented Rock Gnatovich, Chief Operating Officer
of TIBCO Spotfire. "The dataPOWER(r) VSF release further validates our strategy
to enable business partners to quickly develop and distribute specialized
solutions built on our award-winning analytics platform. By leveraging
Spotfire's innovative user experience and extending the platform with rich
semiconductor capabilities, PDF Solutions will be able to help their customers
accelerate yield insight and boost engineering productivity."
