Patent ID: 7843985

Claim:
A light chip having an optical element formed on a first substrate, comprising: a cavity, formed directly within a surrounding resin layer, comprising at least a first mirror, a second mirror and an active layer formed in between the first mirror and the second mirror, wherein the first mirror, the second mirror, and the active layer all have a same width or radius, and having an emission surface on the upper surface; a first electrode and a second electrode for driving the optical element; and a plurality of pad portions, for flip-chip bonding to a second substrate, connected to the first electrode and the second electrode, respectively, wherein the cavity is, seen in a plan view, formed outside a region between the plurality of pad portions, the surrounding resin layer is located beneath the first electrode and has a height that decreases as the surrounding resin layer extends radially outward from the cavity, and a first surface of the active layer is completely disposed upon a first surface of the first mirror and a first surface of the second mirror is completely disposed upon a second surface of the active layer.
