Abstract
An interconnect scheme includes a conductive ink forming a plurality of conductive regions, and a dielectric ink occupying spaces between the conductive regions. The conductive ink and the dielectric ink have substantially identical optical, acoustic, and x-ray absorption properties, thereby making the interconnect scheme tamper-resistant and/or difficult to identify and reverse-engineer using conventional detection methods.
