SEH America is part of the largest producer of semiconductor silicon in the
world, Shin-Etsu Handotai (SEH), Ltd., headquartered in Tokyo, and is an
integral part of the ShinEtsu group
of companies. In the Vancouver, Washington facility, we manufacture
single-crystal silicon ingots, polished and epitaxial wafers, and provide
service and engineering support for customers. Our world-wide reputation for
quality is based on global technical innovation in facilities located in Japan,
Malaysia, Europe, Taiwan and the U.S.A.
SEH is the world-leader in the manufacturing of silicon wafers for the
semiconductor industry. Sliced from an ultra-pure crystalline ingot and then
polished, silicon wafers are processed by our customers through the addition of
circuit patterns arranged in tiny squares commonly referred to as "computer
chips." These chips are then separated and packaged into electronic components
that are at the heart of many products, including computers, lasers, automotive
electronics, telecommunications and many consumer products.
