Claim 0:
1. A method for producing electronic devices, the method comprising:
fixing a die that includes an electronic component with integral contacts to a dielectric substrate, wherein the die is disposed outside of a body of the dielectric substrate such that the die extends above a surface of the dielectric substrate; and
after fixing the die, printing a conductive trace over both the dielectric substrate and at least one of the integral contacts, so as to create an ohmic connection between the conductive trace on the dielectric substrate and the electronic component, wherein printing the conductive trace comprises ejecting droplets of a conductive material onto both the dielectric substrate and the at least one of the integral contacts, wherein ejecting the droplets comprises directing a pulsed laser beam to impinge on a donor film comprising the conductive material, whereby the droplets are ejected by laser-induced forward transfer (LIFT), wherein the die has opposing upper and lower sides and a planar surface connecting the upper and lower sides, wherein the lower side is fixed to the dielectric substrate, wherein the at least one of the integral contacts over which the conductive trace is printed is on the upper side, wherein ejecting the droplets comprises directing the pulsed laser beam to impinge on a first donor film comprising a first metal having a first melting temperature so as to form an adhesion layer on the dielectric substrate along a track of the conductive trace, and then directing the pulsed laser beam to impinge on a second donor film comprising a second metal having a second melting temperature, higher than the first melting temperature, so as to build up the conductive trace over the adhesion layer, wherein ejecting the droplets comprises building up a pillar using the ejected droplets alongside the electronic component from the dielectric substrate to the at least one of the integral contacts, wherein the pillar is non-perpendicular with the dielectric substrate such that the pillar tilts into the planar surface, and wherein at least one of the droplets on the at least one of the integral contacts is adjacent the pillar and connects the at least one of the integral contacts to the pillar.
