Abstract: A multi-chip package includes a substrate with a chip mounting area and a first chip positioned in the mounting area. A spacer is attached to the active surface of the first chip and has a thickness to allow space for wire-bonding the first chip's active surface to the substrate. A second chip is attached to the spacer over the first chip. Conductive metal wires electrically connect the first and second chips to the substrate. A package body is formed by encapsulating the first and second chips and the conductive metal wires. Ends of the spacer extend to the edge the package body. External connection terminals are attached to the bottom surface of the substrate and a method for the manufacturing thereof.

Abstract: A semiconductor chip package includes a semiconductor chip mounted on a top surface of a substrate. A bottom surface of the substrate has ball pads. Bonding pads of the chip are electrically connected to the substrate. Enhanced pads, each having one or more dummy patterns coupled to one or more dummy pads, are preferably formed near edges of the substrate. The semiconductor chip package is mounted on the board by attaching external connection terminals such as solder balls, formed on the ball pads and the dummy pads, to a solder paste coated on ball lands and enhanced lands of the board.
