Abstract
A window-type multi-chip semiconductor package is provided. A first chip and a second chip are mounted on a surface of a substrate formed with an opening, and a third chip is stacked on the first and second chips, wherein a plurality of bonding wires formed through the opening are used to electrically interconnect the chips and electrically connect the chips to the substrate. The chips are encapsulated by a first encapsulant formed on the surface of the substrate, and a second encapsulant is formed on an opposing surface of the substrate for encapsulating the bonding wires. With the chips being mounted on the same surface of the substrate, conductive elements such as bond pads formed on the chips are arranged toward the same direction and facilitate shortening of the bonding wires, thereby enhancing electrical transmission and performances for the semiconductor package.
