Metallised through silicon vias located in the scribe lanes between die are used to create an electrical connection between the front-side and the rear-side of a silicon die. One of the metallisation layers on the front-side of the die comprises portions which extend into the scribe lanes to form capture pads for the through silicon vias. The rear-side of the wafer is metallised and this metallisation may, in some embodiments, be patterned to form tracks or components. The silicon die may be used to create improved package on package devices. In other examples, other substrate materials may be used.
