Abstract:
1. A microdevice having a hermetically sealed cavity to house a microstructure, the microdevice comprising: a substrate having a top side, the substrate having a plurality of conductive traces formed on at least a portion of its top side, the conductive traces providing electrical connection to the microstructure; a conductive cap having a base portion and a sidewall, the sidewall extending outwardly from the base portion to define a recess in the cap; an isolation layer attached between at least the sidewall of the cap and the plurality of conductive traces formed on the top side of the substrate, wherein the isolation layer electrically isolates the cap from the rest of the microdevice; at least one conductive island attached to the substrate and at least one of the plurality of conductive traces; and an isolation trench between the cap and the at least one conductive island; wherein the microstructure is mounted onto the isolation layer within the hermetically sealed cavity, the hermetically sealed cavity being at least partially defined by the recess in the cap, wherein the conductive island is electrically connected to the microstructure through the conductive traces.
