Abstract:
1. A semiconductor system in package (SIP), comprising: a first semiconductor package including a first printed circuit board (PCB), a first semiconductor die being disposed on the first PCB and having conductive posts disposed on an upper surface of the first semiconductor die, and a first molding disposed on the first PCB and being configured to cover the first semiconductor die and the conductive posts, wherein upper surfaces of the conductive posts are exposed out of the first molding; and a second semiconductor package including a second PCB, a second semiconductor die being disposed on the second PCB, and a second molding disposed on the second PCB and being configured to cover the second semiconductor die; wherein a second PCB is directly disposed on both of an upper surface of the first molding and the upper surfaces of the conductive posts; wherein the first and second semiconductor packages are electrically connected to each other through the conductive posts without solder balls therebetween.
