On the basis of this array of products, supported by advanced technological capabilities, Dowa Electronics Materials is working to win the top position in a broad range of industries, and is making vigorous investments in the development of new businesses.Dowa Electronics Materials’ semiconductor products can be divided into three categories: high-purity gallium, gallium arsenide wafers, and LEDs. Dowa Electronics Materials uses high-purity gallium in the production of wafers and LEDs, and markets it outside the company, boasting the top share of the world market. Gallium is produced from by-products of the zinc smelting process at Akita Zinc Co., Ltd., and also in the scrap recycling process. In addition, gallium arsenide wafers show particular strength as substrates for laser applications in the VGF process. Dowa Electronics Materials is the top maker of high-intensity, high-output red and infrared LEDs. LEDs made by Dowa Electronics Materials are used in a number of fields with high growth potential, including advanced medical devices such as blood sensors and cancer treatment equipment, the newest sensors for inkjet printers, and infrared LEDs for infrared communications.
