Abstract:
An embodiment method of forming a package-on-package (PoP) device includes temporarily mounting a substrate on a carrier, stacking a first die on the substrate, at least one of the die and the substrate having a coefficient of thermal expansion mismatch relative to the carrier, and stacking a second die on the first die. The substrate may be formed from one of an organic substrate, a ceramic substrate, a silicon substrate, a glass substrate, and a laminate substrate.

Claim (Index 1):
A package-on-package (PoP) device comprising:\n a substrate having conductive features; a first die over the substrate and electrically coupled to the conductive features of the substrate, wherein the first die comprises:\n a first substrate, a first side of the first substrate facing the substrate, a second side of the first substrate facing away from the substrate; \n through vias in the first substrate extending from the first side of the first substrate to the second side of the first substrate; \n first aluminum pads contacting and extending along the first side of the first substrate; \n second aluminum pads contacting and extending along the second side of the first substrate, wherein each of the through vias is disposed between a respective first aluminum pad and a respective second aluminum pad; \n a first passivation layer along the first side of the first substrate, wherein the first passivation layer covers first portions of the first aluminum pads and exposes second portions of the first aluminum pads; \n a second passivation layer along the second side of the first substrate, wherein the second passivation layer covers first portions of the second aluminum pads and exposes second portions of the second aluminum pads; \n first conductive pillars proximate the first side of the first substrate and electrically coupled to the exposed second portions of the first aluminum pads; and \n second conductive pillars proximate the second side of the first substrate and electrically coupled to the exposed second portions of the second aluminum pads, wherein the first conductive pillars are bonded to the substrate; and \n a second die over the first die and electrically coupled to the first die.
