Business
Sumco Corporation manufactures and sells silicon wafers for the semiconductor industry worldwide. Established in 1999 and headquartered in Tokyo, Japan, the company produces monocrystalline silicon ingots using Czochralski, Magnetic Czochralski and Float-Zone methods; polished wafers up to 300mm in diameter with gettering capabilities; annealed wafers with enhanced crystal perfection; epitaxial wafers featuring vapor phase growth monocrystalline silicon layers; junction isolated wafers incorporating embedding layers for integrated circuits via photolithography, ion implantation and thermal diffusion; silicon-on-insulator wafers with high-insulation oxide layers for high-integration, low-power devices; and reclaimed polished wafers for recycling. Sumco operates production facilities primarily in Japan and Taiwan, with additional sites in the United States, Indonesia, Europe and other regions, serving customers in communication, consumer electronics, automotive, industrial, data center, artificial intelligence and solar energy applications across Japan, the United States, China, Taiwan, South Korea and Europe. In recent developments, the company is launching new 300mm wafer plant facilities and converting existing equipment from non-leading-edge to leading-edge production to meet surging AI-driven demand; reorganizing 200mm and smaller wafer operations for improved efficiency and profitability; and planning to halt wafer production at its Miyazaki plant by 2026 as part of structural reforms to reallocate resources to high-growth leading-edge segments.
