Abstract:
1. A lithographically fabricated apparatus capable of self-assembly to extend at least in part in an out-of-plane direction, the apparatus comprising: a cantilever arm anchored to a substrate at one of its ends and fabricated to provide a cantilever portion that extends from the anchor in a longitudinal direction that is generally parallel to the substrate, the cantilever portion spaced apart from the substrate; at least one post fabricated atop the cantilever portion, the post occupying an in-plane cross-sectional area that is less than an in-plane cross-sectional area of the cantilever portion, a volume of the post shrinking from a first volume to a second volume, less than the first volume, during fabrication thereof; wherein shrinking of the post from the first volume to the second volume causes stress between the post and the cantilever arm, the stress causing, at least in part, the cantilever portion to bend from an in-plane orientation extending in the longitudinal direction to a self-assembled orientation extending at least in part in an out-of-plane direction away from the substrate.
