Abstract: A package structure of a semiconductor device includes a first substrate, a second substrate, and a bonding layer. The bonding layer bonds the first substrate and the second substrate. The bonding layer includes an inner bonding pad pattern and an outer bonding pad pattern formed in a dielectric layer. The outer bonding pad pattern surrounds the inner bonding pad pattern. The outer bonding pad pattern includes first bonding pads, the inner bonding pad pattern includes second bonding pads, a density of the first bonding pads is greater than that of the second bonding pads. The first bonding pads of the outer bonding pad pattern is distributed to form a plurality of pad rings surrounding the inner bonding pad pattern, and the first bonding pads of the plurality of pad rings are aligned in a horizontal direction or a vertical direction.
