Abstract
Some embodiments provide a microdisplay integrated circuit (IC), a substantially transparent protective cover coupled to the microdisplay IC, and a base coupled to the microdisplay IC. Thermal expansion characteristics of the base may be substantially similar to thermal expansion characteristics of the protective cover. According to some embodiments, at least one set of imaging elements is fabricated on an upper surface of a semiconductor substrate, and a base is affixed to a lower surface of the semiconductor substrate to generate substantially negligible mechanical stress between the semiconductor substrate and the base.
