SAN JOSE, Calif. - Crystal IS Inc., a developer of ultraviolet light emitting diodes (UVC LEDs), and Asahi Kasei Corp. announced the signing of a joint development agreement.
Japan's Asahi Kasei has also invested $2 million in Crystal IS. Under the agreement the two companies will create a manufacturing process for large diameter aluminum nitride (AlN) substrates based on Crystal IS proprietary intellectual property.
The development will take place at the Crystal IS facility in Green Island, N.Y. and the program will run in parallel with the company’s UVC LED activities.
“Aluminum nitride substrates are a critical component in the fabrication of UVC LEDs for energy efficient water and air sterilization applications,” said Steven Berger CEO of Crystal IS, in a statement. “Building on our intellectual property to develop manufacturable large diameter substrates is an important step towards high-volume production and long term growth.”
