SAN JOSE, Calif. - Japan's Sumitomo Chemical Co. Ltd. and South Korea's Samsung LED Co. Ltd. have entered into an agreement to establish a joint venture in Korea for research and development, manufacture, and sales of sapphire substrates for LEDs.
This joint venture will initially start with an LED sapphire substrate business. Sumitomo Chemical provides materials such as high-purity alumina used as a raw material in sapphire substrates and liquid crystal polymer used in materials for LED packages.
Last year, Sumitomo Chemical’s wholly-owned subsidiary, Dongwoo Fine-Chem, commenced development of sapphire substrates. Meanwhile, Samsung LED sells LEDs.
