Mattson Technology Increases Etch Product Line Growth With Shipment
to Major Foundry 
Six Semiconductor Manufacturers Now Utilizing Company's Advanced Etch
Tools for Next-Generation Devices 
FREMONT, CA -- (Marketwire) -- 01/09/13 --  Mattson Technology, Inc.
(NASDAQ: MTSN), a leading supplier of advanced semiconductor
processing equipment, today announced that it has shipped an etch
system to a major foundry, the sixth semiconductor manufacturer now
using its etch systems. The etch system will support development and
production of advanced devices at leading-edge technology nodes at
this foundry's R&D facility. 
"As the industry moves to lower technology nodes, the increased cost
of designing and manufacturing integrated circuits becomes even more
of a challenge for our customers," said Rene George, vice president
and general manager of the Plasma Products Group. "To stay on the
leading-edge of each new chip generation, foundries require the most
cost-effective and technologically advanced equipment to achieve the
required return on their investments for expanding fab capacities.
Mattson Technology's etch tool was selected as a result of our
systems' proven track record of achieving optimal process performance
for the most advanced technology nodes while delivering
industry-leading cost of ownership. We are extending our etch
presence in the foundry market with this sixth etch placement, and we
look forward to continue providing leading-edge tools to support its
production ramp of next-generation chips."
