A bonding structure and a method for manufacturing the bonding structure are provided. Multiple chips arranged in an array are formed on a surface of a wafer. Each of the chips includes a device structure, an interconnect structure electrically connected to the device structure, and a first package pad layer electrically connected to the interconnect structure. The first package pad layer is arranged at an edge region of the chip. A chip stack is obtained after bonding and cutting the multiple wafers, and the first package pad layer at the edge region of the chip is exposed.
