Abstract
An integrated circuit including a fabricated die having a cyanate ester buffer coating material thereon. The cyanate ester buffer coating material includes one or more openings for access to the die. A package device may be connected to the die bond pads through such openings. Further, an integrated circuit device is provided that includes a fabricated wafer including a plurality of integrated circuits fabricated thereon. The fabricated wafer has an upper surface with a cyanate ester buffer coating material cured on the upper surface of the fabricated integrated circuit device. Further, a method of producing an integrated circuit device includes providing a fabricated wafer including a plurality of integrated circuits and applying a cyanate ester coating material on a surface of the fabricated wafer. The application of cyanate ester coating material may include spinning the cyanate ester coating material on the surface of the fabricated wafer to form a buffer coat.
