Abstract
A method of manufacture of a package-on-package system includes: providing a package substrate; attaching a semiconductor die to the package substrate; forming an encapsulant around the semiconductor die to have a bottom exposed surface coplanar with a bottom surface of the package substrate and to have a top exposed surface with through openings extending therefrom through the bottom exposed surface; and creating through vias by applying solder into the through openings, the through vias coplanar with the bottom exposed surface of the encapsulant and coplanar with the top exposed surface of the encapsulant.
Claims17
A method of manufacture of a package-on-package system comprising:
- providing a package substrate;
- attaching a semiconductor die to the package substrate;
- forming an encapsulant around the semiconductor die to have a bottom exposed surface coplanar with a bottom surface of the package substrate and to have a top exposed surface with through openings extending therefrom through the bottom exposed surface;
- and
- creating through vias by applying solder into the through openings, the through vias coplanar with the bottom exposed surface of the encapsulant and coplanar with the top exposed surface of the encapsulant.
A method of manufacture of a package-on-package system comprising:
- providing a package substrate with substrate connections;
- attaching a semiconductor die to the package substrate;
- connecting the semiconductor die to the substrate connections in the package substrate using electrical interconnects;
- molding an encapsulant around the semiconductor die using a mold with pins to have a bottom exposed surface coplanar with a bottom surface of the package substrate and to have a top exposed surface, wherein the pins define through openings extending from the top exposed surface through the bottom exposed surface;
- and
- creating through vias by applying solder through a stencil plate with openings aligned to the through openings, the through vias coplanar with the bottom exposed surface of the encapsulant and coplanar with the top exposed surface of the encapsulant.
A package-on-package system comprising:
- a package substrate;
- a semiconductor die attached to the package substrate;
- an encapsulant surrounding at least portions of the package substrate and the semiconductor die, the encapsulant having a bottom exposed surface coplanar with the bottom surface of the package substrate and a top exposed surface;
- and
- through vias extending from the top exposed surface to a bottom exposed surface of the encapsulant, the through vias coplanar with the bottom exposed surface of the encapsulant and coplanar with the top exposed surface of the encapsulant.
