Abstract: An integrated circuit package includes a ceramic ring having an inside cavity for accommodating a semiconductor die. Conductive traces are provided on the ceramic ring so as to serve as power and ground signal busses. Power and ground connection pads on the semiconductor die can be commonly bonded to these conductive traces, which are in turn commonly bonded to selected pins of the lead frame. In addition, an acrylic adhesive is used as a moisture-resistant adhesive.

Abstract: A carrier ring provides a stiffening function for assembling flexible circuits or semi-rigid circuits. The carrier ring is attached to a substrate adapted for attachment of a matrix of semiconductor dies. The carrier ring is provided with mold gates and mold vents for use with a transfer molding step to provide encapsulation for the semiconductor dies. Alignment and indexing marks on the carrier ring allows use of conventional assembly process flows in conventional assembly equipment. The height of the carrier ring also provides a means of providing integrated circuits with a predetermined thickness.

Abstract: A structure and a method provide an assembly for receiving an integrated circuit die. The assembly comprises a heat sink selectively coated with electrically insulative material. The heat sink is attached by one of various methods directly on to the integrated circuit die and a lead frame for external electrical connections. The heat sink is formed as a stepped structure to increase the path of moisture penetration so as to improve moisture resistance and reliability. In one embodiment of the present invention, the electrically insulative material comprises anodized aluminum, which is formed on the heat sink by a vapor deposition step, followed by a hard anodization step. Other electrical insulative material which can be thinly applied on the surface of the heat sink are non-conductive resins and polymers. The heat sink is formed out of copper or a copper alloy, selected for strength and electrical and thermal conductivities.
