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.

A method for fabricating a semiconductor device, the method comprising:
- providing a semiconductor die;
- arranging an electrical connector over the semiconductor die, the electrical connector comprising 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.
A semiconductor device, comprising:
- a semiconductor die;
- and
- an electrical connector arranged over the semiconductor die, the electrical connector comprising a conductive core, an absorbing feature arranged on a first side of the conductive core and facing away from the semiconductor die, and a solder joint arranged on a second side of the conductive core, opposite the first side and coupling the electrical connector to the semiconductor die.
