  • Publication number: 20110193205
    Abstract: A semiconductor device package with an interposer, which serves as an intermediate or bridge circuit of various electrical pathways in the package to electrically connect any two or more electrical contacts, such as any two or more electrical contacts of a substrate and a chip. In particular, the interposer provides electrical pathways for simplifying a circuit layout of the substrate, reducing the number of layers of the substrate, thereby reducing package height and manufacturing cost. Furthermore, the tolerance of the circuit layout can be increased or maintained, while controlling signal interference between adjacent traces and accommodating high density circuit designs. Moreover, the package is suitable for a PoP process, where a profile of top solder balls on the substrate and a package body can be varied according to particular applications, so as to expose at least a portion of each of the top solder balls and electrically connect the package to another device through the exposed, top solder balls.

Because the semiconductor package module does not use solder balls, degradation of solder joint reliability (SJR) can be prevented. Further, the use of a semiconductor package that has already undergone an electrical test can reduce degradation of the yield of a completed semiconductor package module.
