Zusammenfassung:A method including providing a first substrate having a first bond pad and a second bond pad; forming a subassembly comprising securing a second substrate to the first substrate with a ground layer interposed between the first substrate and the second substrate; forming a first trench in the subassembly through the first substrate so that the trench is defined at least in part by a side wall of the first substrate and through at least a portion of the ground layer; and forming a first electrically conductive layer overlying the first bond pad, the side wall of the first substrate and overlying a portion of the ground layer.
