Patent ID: 8484838

Claim:
A method for constructing a capacitance sensing device, the method comprising: forming a plurality of electrodes substantially on a same plane and on a central portion of a substrate, the substrate comprising a central portion and an outer portion; forming a first plurality of conductors on the substrate, each of the first plurality of conductors being connected to and extending from at least one of the plurality of electrodes, wherein ends of the first plurality of conductors extend into the outer portion of the substrate; forming an insulating material on the outer portion of the substrate, wherein the insulating material covers the ends of the first plurality of conductors that extend into the outer portion of the substrate and the insulating material does not extend over the central portion of the substrate; and forming a second plurality of conductors on the insulating material, wherein the second plurality of conductors and the insulating material are configured such that each of the second plurality of conductors is electrically connected to at least some of the first plurality of conductors and is insulated from the others of the first plurality of conductors.
