Abstract: The present invention provides a description for an instrument for creating arrays of metal nanostructures allows on various substrates at the wafer scale. Embodiment methods permit for the formation of individual and arrays of metal alloys of nanostructures by bringing an array of liquid metal droplets droplet in contact with an array of metal patterns by using high precision manipulation mechanism. Top view and side view optical lenses are used to observe the manipulation process and also allow for aligning the metal droplets with film of solid metal patterns. As one example, this instrument is capable of pattering high aspect ratio nanostructures such as silver-gallium (Ag2Ga) nanowires onto prefabricated microstructures. This invention also describes a method for forming arrays of liquid metal droplets on the tip of micro structures by bringing a flexible membrane containing a liquid metal film, in contact with a pattern of microstructures.

Abstract: The present invention provides method for creating point to point metallic contact and bridges between two structures at the nanoscale. Embodiment methods permit for the formation of individual and arrays of silver-gallium nanostructures bridges by mobilizing a gallium microdroplet and bringing in contact with silver coated surface. The invention also describes an example instrument for formation of individual and multiple nanostructure bridges at selective location and orientation. Example structures including multiple nanostructure bridges on the top of each other, suspended nanostructure sensors and actuators, nanowire bonded that provides electrical contacts between nanostructures (e.g. carbon nanotube, Graphene, nanowires) and microelectronic circuits are enabled by this invention.
