Abstract:
A method of metal line deposition using a focused coherent light beam comprising the steps of:(a) forming a donor plate having a donor substrate transparent to the focused coherent light beam, a channel in a donor surface of the donor plate, and a metallic material within the channel to the relative exclusion of areas on the donor substrate outside of the channel;(b) disposing the donor plate in spaced relation to a deposition substrate such that the deposition substrate is adjacent the donor surface of the donor plate;(c) directing the focused coherent light beam through the donor substrate of the donor plate and onto the metallic material in the channel to ablate the metallic material from the channel of the donor plate by discharging ions of the metallic material away from the donor plate and onto the deposition substrate to form the metal line.
