Harris & Harris Group Notes Bridgelux and Toshiba Partnership for GaN on Silicon LED Chips

NEW YORK, May 11, 2012 (GLOBE NEWSWIRE) -- Harris & Harris Group, Inc. (Nasdaq:TINY) noted today that Toshiba Corporation and Bridgelux, Inc., announced the development of an 8" GaN on Silicon LED chip just months after they engaged in a partnership to jointly pursue an innovative technology in the Solid State Lighting (SSL) space. Additionally, Toshiba has made an equity investment in Bridgelux.  This investment will further advance both companies' efforts in the SSL industry, with the goal to enhance Bridgelux's GaN-on-Silicon LED chip technology development efforts based on Toshiba's advanced silicon process and manufacturing technology development efforts.

LED light sources, which are used in everything from televisions and consumer light bulbs, are typically made with a semiconductor -- gallium nitride -- on a layer of sapphire.  Bridgelux has developed a process for depositing gallium nitride on silicon, which the company believes will lead to lower costs by leveraging the existing semiconductor industry infrastructure. Bridgelux's press release can be accessed at http://bridgelux.com/media-center/press-releases/bridgelux-and-toshiba/.
