    摘要: Semiconductor packages with multiple substrates can incorporate cavities in a portion of an upper substrate to minimize or reduce void formations during a molding process. The cavities can be formed substantially over the integrated circuit devices and not over the internal interconnects to further facilitate the flow of the molding compound. The combination with extension members or recesses on a top or exterior surface of the upper substrate can further cut down on bleeding or spill over of the molding compound between adjacent packages and improve device reliability and yield.

    摘要: A method of manufacture of an integrated circuit packaging system includes: providing a substrate; forming a connection post on the substrate, the connection post having a post top and a post side; mounting an integrated circuit die on the substrate, the integrated circuit die having a top die surface; molding an encapsulation on the integrated circuit die and the connection post; and forming a connector recess in the encapsulation by removing the encapsulation around the connection post exposing a portion of the post side.
