Method and system for bonding a chip to a substrate

A method and system for heat bonding a chip to a substrate by means of heat bonding material disposed there between. At least the substrate is preheated from an initial temperature to an elevated temperature below a damage temperature of the substrate. A light pulse applied to the chip momentarily increases the chip temperature to a pulsed peak temperature below a peak damage temperature of the chip. The momentarily increased pulsed peak temperature of the chip causes a flow of conducted heat from the chip to the bonding material, causing the bonding material to form a bond.

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.
