Abstract:
A method for fabricating a flip-chip semiconductor package comprising processing a semiconductor device, for example a semiconductor chip and processing a device carrier, for example a substrate. The semiconductor device comprises bump structures formed on a surface thereof. The substrate comprises bond pads formed on a surface thereof. The semiconductor chip is heated to a chip process temperature. The chip process temperature melts solder portions on the bump structures. The substrate is heated to a substrate process temperature, wherein said substrate process temperature may be different to the chip process temperature. The semiconductor chip is spatially aligned in relation to the substrate to correspondingly align the bump structures in relation to the bond pads. The semiconductor chip is displaced towards the substrate to abut the bump structures with the bond pads to thereby form bonds there between. A system for performing the above method is also disclosed.
