Abstract

A method of packaging a first device having a first major surface and a second major surface includes forming a first layer over a second major surface of the first device and around sides of the first device and leaving the first major surface of the first device exposed, wherein the first layer is selected from the group consisting of an encapsulant and a polymer; forming a first dielectric layer over the first major surface of the first device, forming a via in the first dielectric layer, forming a seed layer within the via and over a portion of the first dielectric layer, physically coupling a connector to the seed layer, and plating a conductive material over the seed layer to form a first interconnect in the first via and over a portion of the first dielectric layer.

Claims (16)

1. A method of packaging a first device having a first major surface and a second major surface, comprising:

forming a dielectric layer over the first major surface a first device;

forming a first via in the dielectric layer;

forming a second via in the dielectric layer;

forming a first seed layer in the first via;

forming a second seed layer in the second via;

placing at least a portion of a first external connector over the dielectric layer, wherein the forming the first seed layer and the placing at least a portion of the first external connector couples the first external connector to the first device;

plating the first seed layer to form a first interconnect;

plating the second seed layer to form a second interconnect; and

coupling the second interconnect to a second external connector.

2. The method of claim 1 , wherein the first external connector and the second external connector are different types of connectors.

3. The method of claim 2 , wherein the first external connector comprises a prefabricated connector and the second external connector comprises a solder ball.

4. The method of claim 3 , wherein the first external connector and the second external connector are both formed over the first major surface of the first device, wherein the first major surface comprises contacts.

5. The method of claim 4 , wherein the first external connectors are formed over a first major surface of the first device, wherein the first major surface comprises contacts, and the second external connector is formed over the second major surface of the first device, wherein the second major surface is opposite the first major surface.

6. The method of claim 1 , wherein the first seed layer is formed after the step of placing at least a portion of the first external connector.

7. The method of claim 1 , wherein the first seed layer is formed before the step of placing at least a portion of the first external connector.
