US Patent 9252030 System-in-packages and methods for forming same

One or more embodiments are directed to a system-in-package (SiP) that includes a plurality of semiconductor chips and an interposer that that are molded in an encapsulation layer together. That is, a single processing step may be used to encapsulate the semiconductor chips and the interposer in the encapsulation layer. Furthermore, prior to setting or curing, the encapsulation layer is able to flow between the semiconductor chips and the interposer to provide further mechanical support for the semiconductor chips. Thus, the process for forming the SiP is reduced, resulting in a faster processing time and a lower cost. Additionally, one or more embodiments described herein reduce or eliminate warpage of the interposer.
