Patent ID: 7006360

Claim:
A stack-type semiconductor package having one or more semiconductor devices contained therein comprising: a printed circuit board (PCB) having a circuit pattern; a first semiconductor memory device (first device) stacked on the PCB and electrically connected to the PCB circuit pattern; a conductive frame having first terminals and second terminals, wherein the first terminals are electrically connected to the PCB circuit pattern; a second semiconductor memory device (second device) stacked on the conductive frame over the first device and electrically connected to second terminals of the conductive frame, wherein the second device is electrically connected to the PCB circuit pattern and the first device via the conductive frame, wherein the conductive frame is a lead frame having a plurality of elongated lead parts, each elongated lead part having a ball land at one end and a lead section at the other end, wherein the ball lands comprise the second terminals and are arranged in a predetermined pattern to correspond to the solder balls of the second device; and further wherein the lead sections comprise the first terminals and are electrically connected to the PCB circuit pattern.
