Abstract
Disclosed is a method of forming an opaque coating on an integrated circuit or multichip module. A coating composition is prepared and then heated to a temperature sufficient to transform the coating composition to a molten state. Next, the molten coating composition is applied to a surface of the integrated circuit device to form an opaque coating that overlies active circuitry on the surface, to prevent optical and radiation based inspection and reverse engineering of the active circuitry.
