Kopin licenses LED-related patents from NCSU

Kopin is continuing its relationship with NCSU by licensing three patents related to the fabrication of LEDs.
Kopin has announced that it has exclusively licensed a patent on domain epitaxy and two patents on cubic ZnMgO and ZnCdO from North Carolina State University (NCSU).

Kopin has been working closely with Professor Jagdish Narayan and his team at NCSU on the development of its CybeLite blue LED products. In November 2002, Kopin and NCSU announced the development of a process for the epitaxial grow of nominally lattice-mismatched materials. The technique is being applied to the formation of very-low resistance ohmic contacts for Kopin’s CyberLite LEDs.

The two patents on cubic ZnMgO and ZnCdO cover the epitaxial growth of these materials on silicon (100) substrates with the aim of creating inexpensive LEDs for integration with microelectronic devices. These materials are seen as important because they can be used to produce LEDs and lasers of any color across the visible spectrum, including the three primary colors needed for white LEDs.

All three patents were invented by Narayan and his team at NCSU. Professor Narayan was named as the John C. C. Fan Family Distinguished Professor of Materials Science and Engineering in May 2003. The endowed chair is named after John Fan, Kopin’s founder and CEO.
