Abstract:
An embodiment package on package (PoP) device includes a molding compound having a metal via embedded therein, a passivation layer disposed over the molding compound, the passivation layer including a passivation layer recess vertically aligned with the metal via, and a redistribution layer bond pad capping the metal via, a portion of the redistribution layer bond pad within the passivation layer recess projecting above a top surface of the molding compound.

Claim (Index 1):
A method comprising:\n forming a passivation layer over a carrier substrate, the passivation layer having a first surface and a second surface, the first surface of the passivation layer being opposite the second surface of the passivation layer, the second surface of the passivation layer facing the carrier substrate; patterning the passivation layer to form a first opening therein, a width of the first opening decreasing as the first opening extends from the first surface of the passivation layer toward the second surface of the passivation layer; depositing a first conductive material along a bottom and sidewalls of the first opening to form a first conductive layer; depositing a second conductive material over the first conductive layer in the first opening to form a second conductive layer; forming a conductive pillar over the second conductive layer; removing portions of the first conductive layer not protected by the conductive pillar and the second conductive layer; attaching an integrated circuit die to the passivation layer adjacent the conductive pillar; encapsulating the integrated circuit die and the conductive pillar with a molding compound; removing the carrier substrate; and recessing the passivation layer to expose a first portion of the first conductive layer disposed on the sidewalls of the first opening.
