1. A method of manufacture of an integrated circuit packaging system comprising:

providing a substrate assembly having a connection path;

mounting a base device over the substrate assembly with a mount layer;

mounting a stack device over the base device and having a stack die and a stack-organic-material;

forming a stack-through-via in the stack-organic-material of the stack device and connected to the stack die and the substrate assembly; and

applying a shield layer directly on a planarized surface of the stack-through-via partially exposed from the stack-organic-material.

2. The method as claimed in claim 1 wherein forming the stack-through-via includes forming the stack-through-via partially exposed from the stack-organic-material.

3. The method as claimed in claim 1 further comprising applying a horizontal barrier around the base device.

4. The method as claimed in claim 1 further comprising attaching a conductive bump on the stack-through-via.

5. The method as claimed in claim 1 wherein mounting the base device includes forming a base-through-via in the base device.

6. A method of manufacture of an integrated circuit packaging system comprising:

providing a substrate assembly having a connection path;

mounting a base device over the substrate assembly with a mount layer;

mounting a stack device over the base device and having a stack die and a stack-organic-material;

forming a stack-through-via in a the stack-organic-material of the stack device and connected to the stack die and the substrate assembly;

applying an encapsulant over the base device and the stack device; and

applying a shield layer directly on a planarized surface of the stack-through-via partially exposed from the stack-organic-material.

7. The method as claimed in claim 6 wherein forming the stack-through-via includes forming the stack-through-via partially exposed from the stack-organic-material and sides of the stack device.

8. The method as claimed in claim 6 further comprising applying a horizontal barrier around the stack die.

9. The method as claimed in claim 6 further comprising attaching a conductive bump on the stack-through-via and substantially exposed from the encapsulant.

10. The method as claimed in claim 6 wherein mounting the base device includes forming a base-through-via in a base-organic-material of the base device.

11. An integrated circuit packaging system comprising:

a substrate assembly having a connection path;

a base device over the substrate assembly with a mount layer;

a stack device over the base device and having a stack die and a stack-organic-material;

a stack-through-via formed in the stack-organic-material of the stack device and connected to the stack die and the substrate assembly; and;

a shield layer directly on the stack-through-via having a substantially flat surface characteristic of a planarization process and partially exposed from the stack-organic-material.

12. The system as claimed in claim 11 wherein the stack-through-via is formed partially exposed from the stack-organic-material.

13. The system as claimed in claim 11 further comprising a horizontal barrier around the base device.
