    摘要: A high efficiency, high yield emitter package is disclosed exhibiting limited wavelength variations between batches and consistent wavelength and emission characteristics with operation. One embodiment of an emitter package according to the present invention comprises a semiconductor emitter and a conversion material. The conversion material is arranged to absorb substantially all of the light emitting from the semiconductor emitter and re-emit light at one or more different wavelength spectrums of light. The conversion material is also arranged so that there is not an excess of conversion material to block said re-emitted light as it emits from said emitter package, said emitter package emitting light at said one or more wavelength spectrums from said conversion material. The semiconductor emitter is preferably a light emitting diode (LED) or laser diode.

    摘要: Methods for fabricating light emitting diode (LED) chips comprising providing a plurality of LEDs typically on a substrate. Pedestals are deposited on the LEDs with each of the pedestals in electrical contact with one of the LEDs. A coating is formed over the LEDs with the coating burying at least some of the pedestals. The coating is then planarized to expose at least some of the buried pedestals while leaving at least some of said coating on said LEDs. The exposed pedestals can then be contacted such as by wire bonds. The present invention discloses similar methods used for fabricating LED chips having LEDs that are flip-chip bonded on a carrier substrate and for fabricating other semiconductor devices. LED chip wafers and LED chips are also disclosed that are fabricated using the disclosed methods.
