Provided are a semiconductor package and a method of manufacturing the semiconductor package, and more particularly, a semiconductor package with bonding wires and a method of manufacturing the semiconductor package. The semiconductor package includes a substrate including a finger, at least one semiconductor chip stacked on the substrate, the semiconductor chip including a chip pad, and a wire which electrically connects the finger with the chip pad, wherein one end of the wire bonds with an upper surface and lateral surfaces of the finger.

Semiconductor package and method of manufacturing the same

A method and apparatus for bonding a wire and a wire bond device formed by the same are disclosed. The method includes providing a carrier with at least a first pad, providing a semiconductor chip having at least the second pad, the at least second pad being smaller than the first a pad, forming a conductive stud bump on the second pad, and forming a bonding wire that has two terminal portions, which are respectively bonded to the first pad and the stud bump to electrically connect the first pad and the second pad. The stud bump is bonded to the second pad by a ball bonding method which uses a wire that has an approximately smaller diameter than the bonding wire. Further, a prominence formed on one end of the terminal portions is provided which has an approximately larger diameter than the stud bump.

Method and apparatus for bonding a wire

Semiconductor chip stack structure and method are provided. A first chip has a first metal bump formed on a first electrode pad. The first chip is attached to and electrically connected to a substrate. The electrical connection is made by a bump reverse bonding method in which one end of a bonding wire is ball-bonded to the substrate and the other end is stitch-bonded to the metal bump. The second chip is stacked on the first chip. The bonding wire is substantially parallel with a top surface of the first chip. Accordingly, the chip stack structure and method minimize a space between the first chip and the second chip, thereby reducing the total height of semiconductor chip stack.
