  • Patent number: 7638365
    Abstract: 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.

    Abstract: Provided are semiconductor device packages and methods for fabricating the same. In some embodiments, the method includes providing a semiconductor chip on a substrate with through electrodes formed in the substrate, and providing a capping layer on the substrate to receive the semiconductor chip in a recess formed in the capping layer. The capping layer is coupled to the substrate by a bonding layer formed on the substrate, and the capping layer covers the semiconductor chip provided on the substrate. The processing of the substrate and the capping layer can be separately performed, thus allowing the material for the capping layer and/or the substrate to be selected to reduce (e.g., to minimize) a difference between the thermal expansion coefficients of the capping layer material and the substrate material.
