TOKYO Sumco Corp. has accelerated a planned expansion of its 300-mm-wafer crystal growth facilities to establish a capacity of 1.4 million raw wafers a month by June 2009.
Sumco, which is vying for the top position in the raw-wafer market with Shin-Etsu Chemical Co. Ltd., currently produces 620,000 to 630,000 wafers per month. "Supply has fallen short of real demand by 20 to 30 percent, so we are doing our best to increase the supply," said a Sumco spokesman.
Sumco purchased Komatsu Electronic Metals Co. Ltd., a wafer operation of Komatsu Ltd., in June and renamed the operation Sumco Techxiv. With the acquisition, Sumco has about a 30 percent share of the wafer market, narrowing the gap with Shin-Etsu's share.
With about an 80 billion ¥ ($673.5 million) investment, Sumco plans to establish montly capacity of 1 million wafers at its Imari plant and 400,000 at Sumco Techxiv. About 100,000 wafers a month will be produced at Sumco Techxiv's Taiwanese plant.
