Abstract

Disclosed is a method of forming a multilayer opaque coating on an integrated circuit or multichip module. First, an opaque coating composition is heated to a molten state and the molten opaque coating composition is applied so as to form an opaque coating that overlies active circuitry on the surface of the integrated circuit or multichip module, to prevent optical and radiation based inspection and reverse engineering of the active circuitry. Further coatings are applied over the opaque coating to shield the active circuitry of the integrated circuit or multichip module from the adverse affects of electromagnetic interference and/or high energy radiation.
