Integrated circuit packaging system with interconnects and method of manufacture thereof
View Patent ↗A method of manufacture of an integrated circuit packaging system includes: forming a post of multiple plating layers having a base end with an inward protrusion, a connect riser, and a top end opposite the base end; positioning an integrated circuit device having a perimeter end facing the connect riser and the inward protrusion; attaching a bond wire directly on the inward protrusion and the integrated circuit device; and applying an encapsulation over the integrated circuit device, the bond wire, the inward protrusion, and around the post, the encapsulation exposing a portion of the base end and the top end of the post.
1. An integrated circuit packaging system comprising;
a post formed of multiple plating layers having a base end with an inward protrusion, a connect riser, and a top end opposite the base end, wherein the connect riser is an integral part of the base end;
an integrated circuit device having a perimeter end facing the connect riser and the inward protrusion,
a bond wire directly on the inward protrusion and the integrated circuit device;
an encapsulation over the integrated circuit device, the bond wire, the inward protrusion, and around the post, a portion of the base end and the top end of the post exposed from the encapsulation, wherein the post includes a conductive protrusion extending from the base end and a portion of the conductive protrusion is exposed from the encapsulation, wherein the portion of the conductive protrusion exposed from the encapsulation is covered with a standoff contact, and wherein the encapsulation includes a component region in the encapsulation, the component region exposed from a base surface of the encapsulation; and
a component protrusion that fills the component region exposed from the base surface of the encapsulation, the component protrusion extends above the base surface, wherein the component protrusion include a component contact, and wherein the component contact is coplanar with the standoff contact.
2. The system as claimed in claim 1 wherein the post includes the inward protrusion of the post formed to have a connect length greater than one-half the enclosed post width.
3. The system as claimed in claim 1 further comprising
a next level integration having a pin;
a stack package having another post; and
connecting the pin in direct contact to the post and to the another post.
4. The system as claimed in claim 1 wherein the encapsulation around the post includes a concave side of the post exposed by the encapsulation.
5. The system as claimed in claim 1 wherein the post includes a through hole formed in the post.
