Abstract:
1. A method for forming a semiconductor device with a bonding pad, the method comprising: providing a first substrate having an upper surface and a bottom surface, the upper surface comprising a device area and a bonding area; forming semiconductor device elements in the device area; forming a bonding pad over the upper surface of the first substrate in the bonding area; forming an interconnect structure comprising a plurality of inter-metal dielectric layers, via plugs and metal patterns within the inter-metal dielectric layers over the bonding pad, wherein a surface of the interconnect structure closest to the bonding pad is the bottom surface of the interconnect structure; bonding a top surface of the interconnect structure to a second substrate; forming an opening from the bottom surface side through the first substrate to expose the bond pad, and attaching a wire bond passing through the opening to the exposed bond pad; wherein the interconnect structure is disposed between the bonding pad and the second substrate.
