    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.

    Abstract: A method includes forming a first substrate including a first dielectric layer and a first metal pad, forming a second substrate including a second dielectric layer and a second metal pad, and bonding the first dielectric layer to the second dielectric layer, and the first metal pad to the second metal pad. One or both of the first and second substrates is formed by forming a first insulating layer, forming an opening in the layer, forming a barrier on an inner surface of the opening, forming a metal pad material on the barrier, polishing the metal pad material to expose a portion of the barrier and to form a gap, expanding the gap, forming a second insulating layer to fill the opening and the gap, and polishing the insulating layers such that a top surface of the metal pad is substantially planar with an upper surface of the polished layer.

    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.
