SAN FRANCISCO Arrowhead Research Corp. said Monday (Feb. 26) that its majority-owned subsidiary, Aonex Technologies Inc. has entered into a collaborative agreement with Kyma Technologies Inc. to develop materials to reduce the cost of gallium nitride (GaN)-based devices such as blue laser diodes and blue light emitting diodes (LEDs).
Under the terms of the agreement, Aonex (Pasadena, Calif.) will provide Kyma (Raleigh, N.C.) with access to its proprietary wafer technology, known as A-Sapph, according to the companies. Kyma will work to leverage the properties of A-Sapph to produce large-area wafers suitable for the manufacture of GaN devices, the companies said.
Competing next-generation DVD formats, Blu-ray Disc and HD DVD, both rely on blue laser diodes. But manufacturing of these devices has proven difficulta blue laser diode glitch delayed the highly anticipated release of Sony Corp.'s PlayStation 3 video gaming console.
Blue LEDs are used as light sources for a wide variety of applications, including back lights for cell phones, and are expected to one day replace conventional incandescent and fluorescent light sources because of their higher efficiencies and longer lifetimes.
"We are delighted to work with the Aonex team," said Keith Evans, Kyma's president and CEO, in a statement. "The combined attributes of Aonex's A-Sapph substrate technology and Kyma's proprietary high growth rate, low defect density GaN crystal growth technology have great potential to reduce the costs of a broad range of high performance nitride semiconductor devices."
