Abstract:
1. A semiconductor device, comprising: an active region configured to emit light upon the application of a voltage thereto; a window layer configured to receive the light emitted by the active region; and a plurality of discrete phosphor-containing regions on the window layer the plurality of discrete phosphor-containing regions containing phosphor particles of a first type of phosphor particle configured to receive light emitted by the active region and to convert at least a portion of the received light to a different wavelength than a wavelength of light emitted by the active region wherein the phosphor-containing regions comprise recesses that extend into and/or through the window layer; and wherein a first plurality of the recesses have a first diameter smaller than or about equal to an average diameter of the first type of phosphor particle in the discrete phosphor-containing regions so that the first plurality of recesses are configured to trap the first type of phosphor particle.
