Abstract:
The present disclosure provides methods for forming semiconductor devices with laser-etched vias and apparatus including the same. In one embodiment, a method of fabricating a semiconductor device includes providing a substrate having a frontside and a backside, and providing a layer above the frontside of the substrate, the layer having a different composition from the substrate. The method further includes controlling a laser power and a laser pulse number to laser etch an opening through the layer and at least a portion of the frontside of the substrate, filling the opening with a conductive material to form a via, removing a portion of the backside of the substrate to expose the via, and electrically coupling a first element to a second element with the via. A semiconductor device fabricated by such a method is also disclosed.
