Abstract
Methods are described to utilize relatively low cost substrates and processing methods to achieve enhanced emissive imager pixel performance via selective epitaxial growth. An emissive imaging array is coupled with one or more patterned compound semiconductor light emitting structures grown on a second patterned and selectively grown compound semiconductor template article. The proper design and execution of the patterning and epitaxial growth steps, coupled with alignment of the epitaxial structures with the imaging array, results in enhanced performance of the emissive imager. The increased luminous flux achieved enables use of such images for high brightness display and illumination applications.
