摘要： Apparatuses and methods for inkjet printing electrical interconnect patterns such as leadframes for integrated circuit devices are disclosed. An apparatus for packaging includes a thin substrate adapted for high temperature processing, and an attach pad and contact regions that are inkjet printed to the thin substrate using a metallic nanoink. The nanoink is then cured to remove liquid content. The residual metallic leadframe or electrical interconnect pattern has a substantially consistent thickness of about 10 to 50 microns or less. An associated panel assembly includes a conductive substrate panel having multiple separate device arrays comprising numerous electrical interconnect patterns each, a plurality of integrated circuit devices mounted on the conductive substrate panel, and a molded cap that encapsulates the integrated circuit devices and associated electrical interconnect patterns. The molded cap is of substantially uniform thickness over each separate device array, and extends into the space between separate device arrays.

摘要： A variety of improved approaches for packaging integrated circuits are described. In one described approach, a multiplicity of die cavities are formed in a plastic carrier. In some preferred embodiments, the die cavities are formed by laser ablation. A multiplicity of dice are placed on the carrier, with each die being placed in an associated die cavity. Each of the dice preferably has a multiplicity of I/O bumps formed thereon. An encapsulant is applied over the carrier to form an encapsulant layer that covers the dice and fills portions of the cavities that are not occupied by the dice. In some preferred embodiments, the encapsulant is an epoxy material applied by screen printing and the dice are not physically attached to the carrier prior to the application of the encapsulant. In these embodiments, the epoxy encapsulant serves to secure the dice to the carrier.

摘要： The present inventions relate to methods and arrangements for using a thin foil to form electrical interconnects in an integrated circuit package. One embodiment of the present invention involves attaching multiple dice to a foil carrier structure. The foil carrier structure is made of a thin foil that is bonded to a carrier. The dice and at least a portion of the metallic foil is then encapsulated with a molding material. The carrier is removed, leaving behind a molded foil structure. The exposed foil is patterned and etched using photolithographic techniques to define multiple device areas in the foil. Each device area includes multiple conductive lines. Afterwards, portions of the conductive lines are covered with a dielectric material and other portions are left exposed to define multiple bond pads in the device area. The molded foil structure can be singulated to form multiple integrated circuit packages.
