Patent ID: 8881373

Claim:
A method for assembling a Radio Frequency Identification (RFID) tag precursor, the method comprising: providing an assembly having an RFID integrated circuit (IC), a nonconductive repassivation layer on a surface of the IC and confined within a perimeter of the surface, and a conductive redistribution layer on the repassivation layer and confined within the perimeter of the surface, in which at least a first portion of the redistribution layer is electrically connected to the IC through a first opening in the repassivation layer; providing a substrate having a first antenna terminal; forming a second opening in a nonconductive barrier present on at least one of the first antenna terminal and the first portion of the redistribution layer with an etchant, where the first opening and the second opening are nonoverlapping; attaching the assembly to the substrate with an adhesive; and forming a first electrical connection between the first antenna terminal and the first portion of the redistribution layer through the second opening.
