Abstract:
A method for fabricating a micro electromechanical device includes providing a first substrate including control circuitry. The first substrate has a top surface and a bottom surface. The method also includes 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, and bonding a second substrate to the first substrate. The method further includes thinning the second substrate to a predetermined thickness and forming a plurality of trenches in the second substrate. Each of the plurality of trenches extends to the top surface of the first substrate. Moreover, the method includes 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.
