Abstract

Methods for forming elements having a predetermined shape and for assembling the elements. In one example of a method, each of the elements includes a functional component which is disposed on a first face of a first substrate. A layer representing a first portion of the first substrate at a second face of the first substrate is removed, leaving a second portion of the first substrate on the first substrate. The second portion is etched through a first patterned mask on a surface of the second portion. The plurality of elements is then released from the first substrate. The plurality of elements may then be combined with a fluid to form a slurry. In another example of a method, the first face is etched vertically in regions adjacent to the edges of the plurality of elements, and regions below the first face are etched laterally, and then the plurality of elements are released from the substrate. Other methods of creating elements having a predetermined shape are described, and methods of using and/or assembling these elements are also described.
