Abstract: An apparatus for material deposition on an acceptor surface includes a transparent donor substrate having opposing first and second surfaces, and a donor film on the second surface. The apparatus additionally includes an optical assembly, which is configured to direct a beam of radiation to pass through the first surface of the donor substrate and impinge on the donor film at a location on the second surface so as to induce ejection of droplets of molten material from the donor film at an angle that is not normal to the second surface at the location onto the acceptor surface.

Abstract: A method for metallization includes providing a transparent donor substrate (34) having deposited thereon a donor film (36) including a metal with a thickness less than 2 μm. The donor substrate is positioned in proximity to an acceptor substrate (22) including a semiconductor material with the donor film facing toward the acceptor substrate and with a gap of at least 0.1 mm between the donor film and the acceptor substrate. A train of laser pulses, having a pulse duration less than 2 ns, is directed to impinge on the donor substrate so as to cause droplets (44) of the metal to be ejected from the donor layer and land on the acceptor substrate, thereby forming a circuit trace (25) in ohmic contact with the semiconductor material.

Abstract: Printing apparatus (20) includes a donor supply assembly (30), which provides a transparent donor substrate (26) having opposing first and second surfaces and a donor film formed on the second surface so as to position the donor film in proximity a target area (28) on an acceptor substrate (22). An optical assembly (24) directs multiple output beams of laser radiation simultaneously in a predefmed spatial pattern to pass through the first surface of the donor substrate and impinge on the donor film so as to induce ejection of material from the donor film onto the acceptor substrate according, thereby writing the predefined pattern onto the target area of the acceptor substrate.

Abstract: Optical apparatus (20) includes a laser (22), which is configured to emit a beam of coherent optical radiation at a specified wavelength along a beam axis. A deflector (24) is configured to intercept and selectably deflect the beam over a range of angles relative to the beam axis. A plurality of diffractive optical elements (DOEs—32, 34, 36, 64, 66, 68) are positioned to receive the deflected beam at different, respective deflection angles within the range and to output respective diffracted beams. Beam-combining optics (42, 74) are configured to receive and deflect the diffracted beams from the DOEs so that all of the diffracted beams are directed along a common output axis toward a target (48).

Abstract: A method for circuit fabrication includes defining a solder bump, including a specified solder material and having a specified bump volume, to be formed at a target location on an acceptor substrate. A transparent donor substrate, having a donor film including the specified solder material, is positioned such that the donor film is in proximity to the target location on the acceptor substrate. A sequence of pulses of laser radiation is directed to pass through the first surface of the donor substrate and impinge on the donor film so as to induce ejection from the donor film onto the target location on the acceptor substrate of a number of molten droplets of the solder material such that the droplets deposited at the target location cumulatively reach the specified bump volume. The target location is heated so the deposited droplets melt and reflow to form the solder bump.

Abstract: A method of producing a conductive path on a substrate including depositing on the substrate a layer of material having a thickness in the range of 0.1 to 5 microns, including metal particles having a diameter in the range of 10 to 100 nanometers, employing a patterning laser beam to selectably sinter regions of the layer of material, thereby causing the metal particles to together define a conductor at sintered regions and employing an ablating laser beam, below a threshold at which the sintered regions would be ablated, to ablate portions of the layer of material other than at the sintered regions.

Abstract: Printing apparatus includes a donor supply assembly, which positions a transparent donor substrate having opposing first and second surfaces and a donor film formed on the second surface so that the donor film is in proximity to a target area on an acceptor substrate. An optical assembly directs one or more beams of laser radiation to pass through the first surface of the donor substrate and impinge on the donor film so as to induce ejection of material from the donor film onto the acceptor substrate. Means are provided to mitigate or compensate for the variation in reflection of the laser radiation across an area of the donor substrate, so as to equalize a flux of the laser radiation that is absorbed in the donor film across the area of the donor substrate.
