Abstract: An integrated circuit package has at least two stacked IC dies (204, 206), where a first IC die (204) couples to a metallization structure directly through solder balls (220) and a second IC die (206) stacked on top of the first die (204) connects to the metallization structure through wire bond connections (228(1)-228(X)). The IC dies (204,206) are electrically coupled to one another through an interior metal layer (210(1)) of the metallization structure. Vias (212) are used to couple to the interior metal layer (210(1)). Optionally a third wire bonded IC die may be stacked on the second IC die (206) and electrically coupled to the first IC die through the interior metal layer (210(1))

Abstract: An electrical connection is formed between a wire electrode (30) comprising a metallic core (32) surrounded by a sheath (34) of insulating material and a metallic contact surface (20) of an integrated circuit. Mechanical force is applied to break the sheath (34) of insulating material and expose part of the metallic core (32) of the wire electrode. A bonding wire (8) made of the same metallic material as the metallic core (32) is provided in a capillary (6), and at least one of electrical charge, heat and ultrasonic vibration is applied to a tip of the bonding wire (8) and the capillary (6) is pressed towards the wire electrode, to melt the tip of the bonding wire to form a bond of metallic material which connects the exposed core of the wire electrode to the metallic contact surface (20) of the integrated circuit. This helps to reduce bond resistance.
