Abstract:
1. A method for fabricating a micro electromechanical device, the method comprising: providing a first substrate including control circuitry, the first substrate having a top surface and a bottom surface; forming an insulating layer on the top surface of the first substrate; removing a first portion of the insulating layer so as to form a plurality of standoff structures; bonding a second substrate to the first substrate, the second substrate having an upper surface and a lower surface; thinning the second substrate to a predetermined thickness; forming a plurality of trenches in the second substrate, each of the plurality of trenches extending to the top surface of the first substrate; filling at least a portion of each of the plurality of trenches with a conductive material; forming the micro electromechanical device in the second substrate; and bonding a third substrate to the second substrate.
