Abstract
A method and apparatus for assembly of small structures is disclosed. The present invention discloses electron beams created from one or more nanotips in an array operated in a field emission mode that can be controlled to apply heat to very well defined spots. The multiple electron beams may be generated and deflected and applied to electron beam heating and welding applications.
