Abstract: A semiconductor package includes main pad structures and dummy pad structures between a first semiconductor chip and a second semiconductor chip. The main pad structures include first main pad structures apart from one another on the first semiconductor chip and second main pad structures placed apart from one another on the second semiconductor chip and bonded to the first main pad structures. The dummy pad structures include first dummy pad structures including first dummy pads apart from one another on the first semiconductor chip and first dummy capping layers on the first dummy pads, and second dummy pad structures including second dummy pads apart from one another on the second semiconductor chip and second dummy capping layers on the second dummy pads. The first dummy capping layers of the first dummy pad structures are not bonded to the second dummy capping layers of the second dummy pad structures.

Abstract: A semiconductor device is provided and includes first and second semiconductor chips bonded together. The first chip includes a first substrate, a first insulating layer disposed on the first substrate and having a top surface, a first metal pad embedded in the first insulating layer and having a top surface substantially planar with the top surface of the first insulating layer, and a first barrier disposed between the first insulating layer and the first metal pad. The second chip includes a second substrate, a second insulating layer, a second metal pad, and a second barrier with a similar configuration to the first chip. The top surfaces of the first and second insulating layers are bonded to provide a bonding interface, the first and second metal pads are connected, and a portion of the first insulating layer is in contact with a side region of the first metal pad.

Abstract: A semiconductor package includes a first semiconductor chip, a second semiconductor chip, first main connection pad structures, and first dummy connection pad structures. The first main connection pad structures are arranged at an interface between the first semiconductor chip and the second semiconductor chip and arranged to be apart from each other by a first main pitch in a first direction parallel to a top surface of the first semiconductor chip, wherein each of the first main connection pad structures includes a first connection pad electrically connected to the first semiconductor chip, and a second connection pad electrically connected to the second semiconductor chip and contacting the first connection pad. The first dummy connection pad structures are arranged at an interface between the first semiconductor chip and the second semiconductor chip, are arranged to be apart from the first main connection pad structures, and are arranged to be apart from each other by a first dummy pitch in the first direction, the first dummy pitch being greater than the first main pitch.
