Sumitomo Electric has successfully developed Flexible Printed Circuit (FPC) for LED applications that can tolerate high temperature of 150 degrees Celsius, according to a report by Nikkei.

Major step in joint partnership to develop market of GaN substrates for high-performance LED lighting applications. Soitec (Euronext), a world leader in generating and manufacturing revolutionary semiconductor materials for the electronics and energy industries, and Sumitomo Electric Industries, Ltd., a leading worldwide provider of compound semiconductor materials, have signed a licensing and technology-transfer agreement under which Sumitomo Electric will use Soitec’s proprietary Smart Cut™ technology to manufacture engineered gallium nitride (GaN) substra...

Recently, Japan's Sumitomo Electric Industries Ltd. is said to develop the world’s first 6-inch diameter gallium nitride (GaN) substrates for white LEDs. Presently, the white LED market has been growing using 2- to 4-inch sapphire substrates. As an alternative to sapphire, Sumitomo Electric began production of 2-inch diameter GaN substrates designed for use in white LEDs.
