Patent ID: 8093102

Claim:
A process of forming an electronic device comprising: attaching a first substrate to a first handling substrate, wherein the first substrate includes a bulk semiconductor material, a first plurality of die locations including a first die location including a first terminal at a first front side surface of the first die location, and, after attaching the first substrate, the first front side surface is adjacent to the first handling substrate; removing a portion of the first substrate after attaching the first substrate to expose a first back side surface, wherein the first back side surface is separated from a first front side surface by a first thickness; forming a first through via at the first die location; forming a first electrical connection between a second terminal at a second front side surface of a second die and the first terminal of the first die, wherein: forming the first electrical connection includes electrically connecting the second terminal and the first through via to each other; the second die is a singulated die during formation of the first electrical connection; the second die includes a second back side surface spaced apart from a second front side surface by a second thickness; and the first thickness is less than half the second thickness; singulating the first die from the first substrate while the first handling substrate is attached to the first substrate; and removing the first handling substrate after singulating the first die from the first substrate.
