摘要:
An integrated circuit device includes a semiconductor structure, a through-silicon-via (TSV) structure that penetrates through the semiconductor structure and a connection terminal connected to the TSV structure. A metal capping layer includes a flat capping portion that covers the bottom surface of the connection terminal and a wedge-shaped capping portion that is integrally connected to the flat capping portion and that partially covers a side wall of the connection terminal. The metal capping layer may be formed by an electroplating process in which the connection terminal is in contact with a metal strike electroplating solution while a pulse-type current is applied.
摘要:
Semiconductor devices having stacked structures and methods for fabricating the same are provided. A semiconductor device includes at least one single block including a first semiconductor chip and a second semiconductor chip stacked thereon. Each of the first and second semiconductor chips includes a semiconductor substrate including a through-electrode, a circuit layer on a front surface of the semiconductor substrate, and a front pad that is provided in the circuit layer and is electrically connected to the through-electrode. The surfaces of the semiconductor substrates face each other. The circuit layers directly contact each other such that the semiconductor chips are bonded to each other.

Provided are a semiconductor device, a semiconductor package, and an electronic system. The device includes a substrate having a front side and a back side disposed opposite the front side. An internal circuit is disposed on or near to the front side of the substrate. Signal I/O through-via structures are disposed in the substrate. Back side conductive patterns are disposed on the back side of the substrate and electrically connected to the signal I/O through-via structures. A back side conductive structure is disposed on the back side of the substrate and spaced apart from the signal I/O through-via structures. The back side conductive structure includes parallel supporter portions.
