Siliconix and STMicroelectronics Announce License Agreement for
New Double-Sided Cooling MOSFET Packaging Technology
GENEVA and SANTA CLARA, Calif., March 10 /PRNewswire-FirstCall/ --
STMicroelectronics (NYSE:STM) and Siliconix incorporated (NASDAQ:SILI), an
80.4%-owned subsidiary of Vishay Intertechnology, Inc. (NYSE:VSH), today
announced that the two companies have concluded an agreement whereby ST will
license from Siliconix a new power MOSFET packaging technology that provides
superior thermal performance via top and bottom heat dissipation paths in
systems using forced air cooling.
Offered by Siliconix under the PolarPAK(TM) name, the new package's leadframe
and plastic encapsulation are similar to those used for most standard power
MOSFET packages, ensuring good die protection and easy handling in
manufacturing. Yet compared with the standard SO-8, the PolarPAK package
dissipates heat so efficiently that it can handle twice the current within the
same footprint dimensions.
"With the size of dc-to-dc converters continuing to shrink, it has become a
challenge to dissipate the heat generated by various components on the PCB,"
said Ian Wilson, Manager of the Power MOSFET Division, STMicroelectronics.
"Advances in packaging need to be developed in tandem with silicon technology
improvements. The PolarPAK package, with its superior thermal handling
capability, represents a remarkable evolution in assembly technology allowing
designers to increase efficiency and power density. This package technology
will complement ST's range of STripFETTM MOSFETs optimized for power conversion
in computer, datacom, and telecom applications.
"By working together with Siliconix we will achieve the greater market
acceptance of this new package necessary to enable cost-effective solutions,"
said Carmelo Papa, Corporate Vice President and General Manager of the
Microcontroller, Linear and Discretes Product Group, STMicroelectronics. "We
are strongly committed to the computer and telecom segments, where we want to
be an important player through continuous innovation."
"Siliconix power MOSFET innovations include the industry's first trench power
MOSFETs and a wide range of package types that maximize power density and
thermal performance," said Dr. Felix Zandman, Vishay Chairman and Chief
Technical and Business Development Officer, and Dr. Gerald Paul, Vishay
President and CEO. "PolarPAK is the latest in a long line of such technology
milestones that have made Siliconix and Vishay industry leaders, and this new
agreement with STMicroelectronics is a proud moment for us."
"In signing this agreement with STMicroelectronics, we are taking a significant
step towards the adoption of PolarPAK as an industry-standard package by giving
our customers the flexibility of being able to design with a multi-source
solution," said Dr. King Owyang, Siliconix President and CEO. "We are proud to
have a semiconductor industry leader such as ST recognize the benefits that
PolarPAK can bring to a wide range of power MOSFET applications."
By delivering superior thermal performance and reducing package-related losses,
the 5mm by 6mm PolarPAK package allows designers to create smaller, more
compact circuit designs with a lower component count. With a height dimension
of just 0.8 mm, half the height of the SO-8, the PolarPAK package enables end
products that are thinner as well.
