Patent ID: 7675464

Claim:
A method for making a double-sided electronic device on a semiconductor substrate having one or more pre-formed connection holes through the substrate, comprising the steps of: a) forming a first metal pattern on a first side of the substrate, including in the connection holes, the first metal pattern comprising a first coil and at least one first shunt bar connecting at least two loops in the first coil, wherein forming said first metal pattern comprises printing a first ink pattern comprising a plating material and a solvent, said plating material comprising an organometallic compound or suspension of metal nanoparticles which, after heating sufficiently to remove substantially all carbon-based material, provides a surface on which the metal can be electroplated or electrolessly plated; b) forming a second metal pattern on a second side of the substrate, in alignment with the connection holes, the second metal pattern comprising a second coil and at least one second shunt bar connecting at least two loops in the second coil, wherein the first metal pattern is coupled to the second metal pattern through a connection formed in said connection hole; and c) electrically disconnecting the first and second shunt bars.
