SUMCO, a global leader in the semiconductor silicon wafer market, has announced a significant strategic shift in its production expansion plans. Due to a persistent downturn in silicon wafer demand and intensifying international competition, the company has decided to postpone the construction of its new 300 millimeter wafer manufacturing facility in Yoshinogari. Instead, SUMCO will pivot its capital investment toward enhancing the capabilities of its existing production hubs in Imari, Kyuragi, and Yonezawa.
This tactical realignment is driven by the need for operational efficiency in a volatile market. The investment will focus on upgrading crystal growth and processing stages. Specifically, the Imari plant is projected to reach a processing capacity of 94,000 wafers per month by March 2031. The Kyuragi facility aims for a crystal growth capacity of 58,000 wafers by November 2030 and a processing capacity of 125,000 wafers by March 2031. Meanwhile, the Yonezawa plant is scheduled to achieve a crystal growth capacity of 58,000 wafers by January 2028.
Notably, the anticipated government subsidies for these projects are expected to be significantly reduced from the initial 75 billion yen to approximately 19.3 billion yen. This decision reflects the broader semiconductor industry trend where manufacturers are prioritizing the "brownfield" optimization of current assets over "greenfield" expansion to mitigate financial risks during a period of inventory adjustment for high-performance computing and memory chips.
