Abstract:
1. An electronic device comprising: a material body designed for use in an electronic device, the material body having a surface; and a contact structure supported by at least a portion of the surface of the material body, wherein the contact structure comprises: a patterned non-ohmic layer comprising a plurality of non-ohmic portions; and a patterned conductive layer comprising at least one conductive portion disposed on more than one of the non-ohmic portions and having a first end and a second end, the at least one conductive portion extending from a first conductive pad at the first end, wherein the first and second ends define a length of the at least one conductive portion, and wherein the contact structure has a contact resistance that varies non-linearly along the length of the at least one conductive portion, wherein the shape of a non-ohmic portion and/or the at least one conductive portion is non-liner, and wherein at least a portion of the shape of the non-ohmic portion and/or the at least one conductive portion can be defined by a step function.
