  • Integrated color LED chip
    Patent number: 6882101
    Abstract: A method and apparatus for achieving multicolor displays using an integrated color chip is provided. The integrated color chip contains one or more multicolor generation sites on a single substrate. Each multicolor generation site is comprised of two or more light emitting regions in close proximity to one another, the number of light emitting regions per site dependent upon the number of required colors. The active light generation system for each light emitting region, e.g., an LED, is preferably identical in device structure although size and shape may vary. In order to achieve the desired colors, one or more light conversion layers are applied to individual light emitting regions. Each light emitting region may also include index matching layers, preferably interposed between the outermost surface of the light emitter and the light conversion layer, and protective layers.

  • Compound semiconductor rectifier device structure
    Patent number: 6545298
    Abstract: A rectifier structure that exhibits a low turn-on voltage and allows rapid switching without ringing is provided. The structure utilizes a thin epitaxial layer interposed between the two layers comprising the rectifier junction. Preferably the epitaxial layer is of the same conductivity as the underlying layer while being comprised of the same material as the outermost layer.
