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.
David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
