Semiconductor device and method of forming a PoP device with embedded vertical interconnect units
First Claim
1. A semiconductor device, comprising:
- a substrate including a conductive via formed through the substrate;
a plurality of first vertical interconnect structures disposed over the substrate;
a plurality of second vertical interconnect structures disposed over a first portion of the plurality of first vertical interconnect structures;
a first semiconductor die disposed over a second portion of the plurality of first vertical interconnect structures and adjacent to the plurality of second vertical interconnect structures; and
an encapsulant deposited around the first semiconductor die and around the plurality of first vertical interconnect structures and around the plurality of second vertical interconnect structures with an opening in the encapsulant extending to the plurality of second vertical interconnect structures.

Abstract
A semiconductor device has a substrate. A plurality of conductive vias is formed through the substrate. A conductive layer is formed over the substrate. An insulating layer is formed over conductive layer. A portion of the substrate is removed to expose the conductive vias. A plurality of vertical interconnect structures is formed over the substrate. A first semiconductor die is disposed over the substrate. A height of the vertical interconnect structures is less than a height of the first semiconductor die. An encapsulant is deposited over the first semiconductor die and the vertical interconnect structures. A first portion of the encapsulant is removed from over the first semiconductor die while leaving a second portion of the encapsulant over the vertical interconnect structures. The second portion of the encapsulant is removed to expose the vertical interconnect structures. A second semiconductor die is disposed over the first semiconductor die.
