Abstract:
A device comprising:a structure that has a plurality of substrates bonded together; wherein the plurality of substrates includes a first substrate which comprises a semiconductor substrate and which has a first side, a second side, and an opening passing through the semiconductor substrate from the first side to the second side, wherein the first substrate comprises circuitry which comprises a conductor present in the opening, the conductor extending to the second side of the first substrate and being exposed on the second side of the first substrate; wherein the structure further comprises a component which includes at least a portion of the first substrate and/or is attached to the first substrate, and at least a portion of the component is located at a surface of the first substrate on the first side of the first substrate; wherein the component is to co-operate with said circuitry so as to perform an optical function and/or a magnetic function and/or to move and/or deform; wherein the plurality of substrates comprise a second substrate bonded to the first side of the first substrate, wherein the second substrate does not contain any electronic circuitry coupled to the circuitry in the first substrate.
