<Products that command the top shares of their world markets>
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.
<Many applications for powder materials technology are emerging.>
Dowa Electronics Materials boasts a commanding share of the world market for metal powders used in videotape for broadcasting stations and data storage tape for computer use.
The company has led the industry since the launch in 1984. The characteristics and quality of its cutting-edge superfine metal powders are without peer, as is its ability to ensure prompt delivery in any quantity.
The company has succeeded in developing the next-generation of metal powders, with a particle size of 30 nanometers (0.03 micrometers). Its research and development in the area of higher-capacity recording media is also advancing steadily. The bests of Dowa Electronics Materials’ nanotechnologies are concentrated in this area.
The company has the largest share of the world market for the ferrite powder used in the bond magnets for magnetic rollers used in printers and copiers. Its powdered iron materials have many applications, including carrier powder for copiers and other devices, welding rods, disposable body warmers, and powder metallurgy.
Special iron powders developed by Dowa Electronics Materials are used in Dowa’s soil remediation business, and are highly effective in handling difficult remediation tasks such as contamination by VOCs.
<Technological expertise to meet the need for advanced materials>
Dowa Electronics Materials has developed a number of products in the field of electronic materials. The company has a 70% share of the world market for silver oxide for the button batteries used in wristwatches and other devices, and is one of the world’s leading suppliers of zinc powder for alkaline batteries.
In addition, the company is engaged in the manufacture of silver powder and other conductive materials.
