ABSTRACT:
First and second components may be precisely attached to form an apparatus. In an example embodiment, a first component includes a first field emission structure, and a second component includes a second field emission structure. The first and second components are adapted to be attached to each other with the first field emission structure in proximity to the second field emission structure such that the first and second field emission structures have a predetermined alignment with respect to each other. Each of the first and second field emission structures include multiple field emission sources having positions and polarities relating to a predefined spatial force function that corresponds to the predetermined alignment of the first and second field emission structures within a field domain. The first and second field emission structures are configured responsive to at least one precision criterion to enable a precision attachment.
