Popis: | A 0.13um Cu-Al hybrid backend between a dual damascene process with Cu line and a conventional process with Al line is introduced in this paper. First 3 metal layers (M1~M3) interconnects with Cu line for process capability and circuit speed concern. Whereas following metal layers (M4~M7) interconnects with Al line for cost concern. The interconnection via between Cu and Al interface is the key process for Cu-Al hybrid process. This paper mainly focused on via process study between Cu and Al interconnection. |
