Abstract: A stacked structure of integrated circuits having spacer elements includes a substrate, a spacer element, a lower-layer integrated circuit, an upper-layer integrated circuit, and a molding layer. The substrate includes an upper surface on which the spacer element and the lower-layer integrated circuit are arrayed with each other. The lower-layer integrated circuit includes a solder-pad region and a non-solder-pad region adjacent to the spacer element. The upper-layer integrated circuit is disposed on the spacer element, and covers partly over the non-solder-pad region of the lower-layer integrated circuit. Therefore, the overall height of the stacked structure of integrated circuits can be lowered, making the packaging process simplified, the manufacturing process more stable, and the yield rate of production will be raised.
