  • Publication number: 20090186446
    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.
