Patent ID: 7078790

Claim:
A semiconductor device comprising: a first semiconductor die having opposing first and second sides, the first semiconductor die comprising: at least two first integrated circuit devices; a first conductive structure electrically coupled between the at least two first integrated circuit devices, where the first conductive structure is disposed at least partially through the first semiconductor die and exposed at the first side of the first semiconductor die; a second semiconductor die having opposing first and second sides, the second semiconductor die comprising: at least two second integrated circuit devices; a second conductive structure electrically coupled between the at least two second integrated circuit devices, where the second conductive structure is disposed at least partially through the second semiconductor die and exposed at the second side of the second semiconductor die, wherein the first semiconductor die is stacked on top of the second semiconductor die such that the first conductive structure at the first side of the first integrated circuit die is aligned with, and electrically coupled to, the second conductive structure at the second side of the second semiconductor die.
