A chip stack package includes a substrate, a plurality of chips, a plurality of adhesive layers and a plug. The substrate has a wiring pattern and a seed layer formed on the wiring pattern. Each of the chips has an electrode pad and a first through-hole that penetrates the electrode pad. The chips are stacked such that the first through-holes are aligned on the seed layer of the substrate. The adhesive layers are interposed between the substrate and one of the chips, as well as between the chips. Each of the adhesive layers has a second through-hole connected to the first through-hole. The plug fills up the first through-holes and the second through-holes and electrically connects the electrode pads to the wiring pattern of the substrate. A cross-sectional area of the plug in the second through-holes may be larger than that of the plug in the first through-holes.

摘要:
Provided is a stacked chip package and a method for forming the same. A spacer is formed on a side of an upper chip. A conductive line is formed on the spacer to electrically connect upper and lower chips. The reliability of the stacked chip package is improved because wire bonding is not used to electrically connect the upper and lower chips. Further, the overall size of the stacked chip package can be reduced as the height of bonding wire loops does not contribute to the overall stacked chip package height.
