In its effort to meet the ever-increasing demands of consumer technology,
the semiconductor industry has long been preoccupied with smaller transistors
and larger silicon wafers. While these are important tactics, opportunities
for increasing efficiency, becoming more agile, and minimizing waste are often
overlooked in manufacturing processes, according to Thomas Sonderman, vice president
of manufacturing systems and technology at GLOBALFOUNDRIES.
At SEMICON West 2009, Sonderman is calling for a renewed focus on operational
agility in the semiconductor manufacturing industry, particularly in light of
increased pressure to move to processes based on 450 millimeter (mm) wafers.
“The rush to 450mm suggests a lack of ideas for improving fab productivity,”
Sonderman said. “At GLOBALFOUNDRIES, we see a tremendous amount of headroom
left in the 300mm process. We are tapping our expertise in lean manufacturing
to extend the lifecycle of the industry’s current 300mm investments, and
we are investing more than $4 billion in a new, state-of-the-art 300mm fab in
upstate New York because we are confident in our ability to get the most out
of this technology generation.”
Sonderman will be participating today in the SEMICON West Foundry Summit, a
two-hour panel discussion on the market strategies, technologies, capital spending,
and other strategic plans of the world's major chip foundries. He cites GLOBALFOUNDRIES’
rapid transition and time to mature yield at the 45 nanometer (nm) process node
as a model for operational efficiency in the industry.
During the transition to 45nm, GLOBALFOUNDRIES achieved the fastest time to
mature yield of any process in its history, while simultaneously implementing
a complex new form of lithography—immersion lithography—ahead of
all other semiconductor manufacturers. Immersion lithography allows for enhanced
microprocessor design definition and manufacturing consistency by placing a
fluid, instead of air, between the final element of the lens of a lithographic
exposure tool and the wafer.
All wafer starts in Fab 1, Module 1 have now been converted to 45nm—a
process that is proving to deliver few defects, low leakage, and high performance.
GLOBALFOUNDRIES and AMD recently announced the launch of a six-core processor
codenamed “Istanbul,” which was manufactured using the 45 nm process.
“Istanbul” is the most complex processor ever designed by AMD, and
GLOBALFOUNDRIES’ manufacturing agility allowed AMD to deliver “Istanbul”
five months ahead of schedule.
“The agility and execution of our design and engineering teams combined
with the leading-edge manufacturing of GLOBALFOUNDRIES made possible an early,
well-executed delivery of Six-Core AMD Opteron™ processors to customers,”
said Rick Bergman, senior vice president and general manager of the AMD Products
Group. “As our silicon designs get ever more complex, it is critical to
retain this close collaboration and reliable execution as we deliver the next
wave of processing innovation on the x86 platform.”
A key to GLOBALFOUNDRIES operational agility is a model based on highly automated
decision-making and “lean” manufacturing principles, called Automated
Precision Manufacturing (APM). APM allows GLOBALFOUNDRIES to precisely tune
manufacturing operations to align production with customer demand—all
while minimizing waste and reducing cycle time, inventory, and ultimately costs.
APM will be taken to the next level with the construction of Fab 2—an
estimated $4.2 billion project to build the world’s most advanced 300mm
semiconductor foundry in Saratoga County, N.Y.
“When Fab 2 begins volume production in approximately 2012, it will be
part of an integrated global network linked by the next generation of APM,”
said Norm Armour, vice president and general manager of GLOBALFOUNDRIES Fab
2. “The next generation of APM will feature interoperable technologies
across multiple fabs and the implementation of lean processes in all aspects
of manufacturing, from the front end of the supply chain to the final wafers
out the door of the fab.”
Armour will participate today in the annual SEMI Press Luncheon at SEMICON
West, where he will present a history of the Fab 2 project and an overview of
the capabilities of the new leading-edge facility, which is being designed to
support 28/22nm process technologies.
