Abstract
A method for fabricating a semiconductor device includes providing a semiconductor die, arranging an electrical connector over the semiconductor die, the electrical connector including a conductive core, an absorbing feature arranged on a first side of the conductive core, and a solder layer arranged on a second side of the conductive core, opposite the first side and facing the semiconductor die, and soldering the electrical connector onto the semiconductor die by heating the solder layer with a laser, wherein the laser irradiates the absorbing feature and absorbed energy is transferred from the absorbing feature through the conductive core to the solder layer.
