Abstract
A reflective semiconductor device includes integrated circuitry disposed in a semiconductor layer. A first plurality of mirrors is formed in a mirror layer over the semiconductor layer, and each of the first plurality of mirrors is spaced apart from one another by at least a uniform width. A thin dielectric film layer covers sidewalls of the first plurality of mirrors and the semiconductor layer in the regions between the spaced apart first plurality of mirrors. A second plurality of mirrors are formed in the mirror layer between the thin dielectric film layer covered sidewalls of the first plurality of mirrors and over the thin dielectric film layer covering the semiconductor layer. Each one of the first and second plurality of mirrors has the uniform width, and is coupled to the integrated circuitry disposed in the semiconductor layer.
