アキコーポレーション Company Profile

We handle everything related to solar cells, from raw materials to intermediate products and silicon wafers.

Our business primarily focuses on high-purity silicon products, with approximately 35% related to solar cells, 60% related to semiconductor device front-end processes, and 5% consisting of other rare earths, rare metals, and non-ferrous metals. Not limited to transactions within Japan, we conduct direct transactions with overseas manufacturers and users for all product categories, delivering the most cost-effective and optimal product range to our customers. In the semiconductor sector, we manufacture and provide contract processing from high-purity polycrystalline silicon, which is the raw material for single crystals, to the front-end processes of devices. In particular, regarding silicon wafers, we manufacture and sell not only test wafers for device and equipment manufacturers but also ultra-high-precision development wafers, ultra-high-resistance and ultra-low-resistance wafers for university research institutes, and prime wafers for special applications.
