A method for fabrication includes providing a donor sheet, including a donor substrate, which is transparent in a specified spectral range, a sacrificial layer, which absorbs optical radiation within the specified spectral range and is disposed over the donor substrate, and a donor film, which includes a paste and is disposed over the sacrificial layer. The donor sheet is positioned so that the donor film is in proximity to a target location on an acceptor substrate. A pulsed laser beam impinges on the sacrificial layer with a pulse energy and spot size selected so as to ablate the sacrificial layer, thus causing a viscoelastic jet of the paste to be ejected from the donor film and to deposit, at the target location on the acceptor substrate, a dot having a diameter less than the spot size of the laser beam.

A leadframe has a die pad area and an outer layer of a first metal having a first oxidation potential. The leadframe is placed in contact with a solution containing a second metal having a second oxidation potential, the second oxidation potential being more negative than the first oxidation potential. Radiation energy is then applied to the die pad area of the leadframe contacted with the solution to cause a local increase in temperature of the leadframe. As a result of the temperature increase, a layer of said second metal is selectively provided at the die pad area of the leadframe by a galvanic displacement reaction. An oxidation of the outer layer of the leadframe is then performed to provide an enhancing layer which counters device package delamination.
