New LED Shipper and Purification Solutions From Entegris on Display at 2011
SEMICON China

BILLERICA, Mass., March 14, 2011 (GLOBE NEWSWIRE) -- Entegris, Inc.
(Nasdaq:ENTG) announced today that it will showcase its latest solutions for
semiconductor and LED manufacturers at the 2011 SEMICON China event this week at
the Shanghai New International Expo Center. To meet LED manufacturers'
increasing need for more improved production, Entegris will demonstrate how its
new Ultrapak(R) 150 mm Thick Wafer Shipper and Aeronex(R) gas purification
systems can help manufacturers improve yields by enhancing and preserving wafer
integrity.

The Ultrapak(R) 150 mm Thick Wafer Shipper is designed for shipping the 1.3 mm
thick wafers commonly used in LED chip manufacturing. This polypropylene shipper
secures wafers to limit rotation, reduce particle contamination and prevent
damage or breakage.

"Through collaboration with leading LED manufacturers, Entegris identified key
modifications for its widely-used semiconductor shipper that ideally suit the
unique needs of the LED industry," said William Shaner, vice president and
general manager for Entegris' Microenvironments Division. "We combined their
input with more than 30 years of Entegris' wafer shipping experience to design
the most protective shipper for these critical substrates."

Specific modifications include improving wafer spacing and pitch to fit wafers
that are thicker than standard silicon wafers. The design also features a new
secondary packaging system to support and protect the heavier load. The new
shipper expands Entegris' current line of LED wafer handling products which
includes a multiple wafer shipper for thin wafers, single wafer shippers and
multiple wafer carriers used for in-fab processing.

In addition to the Ultrapak shipper, Entegris will be showing its Aeronex line
of gas purification solutions for High Brightness LED (HBLED) manufacturing
applications. These systems provide reliable gas purification for maximum
uptime, enabling manufacturers to produce HBLEDs with the highest
photoluminescence peaks and luminous efficiencies. The multi-bed design allows
continuous supply of purified gas and is available in several flow ranges for
nitrogen, hydrogen and ammonia.
