Beschreibung
Zusammenfassung:	A nonconductive, organic stabilization layer deposited on an RFID IC provides a consistent and predictable mounting distance between the RFID IC and its antenna layer or a strap, thereby ensuring a consistent and predictable mounting capacitance between circuits of the RFID IC and an antenna formed on the inlay or the strap. Openings in the stabilization layer enable electrical connection between the antenna pads of the RFID IC and the terminals of the inlay antenna or strap contacts through bumps formed on the antenna pads, through a conductive redistribution layer formed on the stabilization layer (when the inlay or strap is attached to the RFID IC by means of an anisotropic conductive layer), or through a capacitive connection to the inlay antenna or strap (when the inlay or strap is attached to the RFID IC by means of a nonconductive layer).
