Abstract

A bonding structure and a manufacturing method therefor. A first hybrid bonding structure is formed on a first wafer; an interconnection structure and a second hybrid bonding structure are formed on the front surface of a second wafer. The first wafer and the second wafer are bonded by means of the first hybrid bonding structure and the second hybrid bonding structure, a gasket electrically connected to the interconnection structure is formed on the back surface of the second wafer, and the interconnection structure below the gasket and a second conductive bonding pad in the second hybrid bonding structure are provided in a staggered manner in the horizontal direction. According to the solution, the interconnection structure and the second conductive bonding pad are arranged in a staggered manner, so that recesses generated by structural stacking are avoided, and device failure caused by the recesses is further avoided.
