Abstract: Electronic apparatus, systems, and methods include a semiconductor layer bonded to a bulk region of a wafer or a substrate, in which the semiconductor layer can be bonded to the bulk region using electromagnetic radiation. Additional apparatus, systems, and methods are disclosed.

Abstract: A simple to manufacture conductor structure is described which requires only a small number of process steps. The conductor structure contains a structured, first insulating layer to which a first passivation layer is applied. A layer of conductive material is applied thereto and in turn a second passivation layer is applied to the layer of conductive material. A hard mask is applied to the second passivation layer. The layer of conductive material is removed in regions defined by the hard mask. The first passivation layer is removed in the regions defined by the hard mask by sputtering and is at least partially deposited again on the side wall of the layer of conductive material.
