Claim:
1. A method of MEMS device fabrication, comprising: etching a plurality of trenches into a substrate wafer; applying an insulating layer to a surface of the substrate wafer; filling the plurality of trenches with a MEMS base material; applying a second insulating layer to the surface of the substrate wafer; depositing a layer of a first conductive material surface of the substrate wafer; patterning the layer of a first conductive material; applying a third insulating layer to the surface of the substrate wafer; patterning the third insulating layer; depositing a layer of a second conductive material to the surface of the substrate wafer; patterning the layer of a second conductive material; etching into the substrate wafer to create a plurality of holes in the substrate wafer; and etching into the substrate wafer through the plurality of holes, wherein the etching detaches the MEMS device from the substrate wafer.
