  • Patent number: 11967571
    Abstract: A semiconductor structure and a method of fabricating therefor are disclosed. A second contact pad (500) is arranged lateral to a first contact pad (420) in an interconnect structure (400). As a result, during fabrication of the interconnect structure (400), the first contact pad (420) will not be present alone in a large bland area, due to the presence of the second contact pad (500). Thus, a pattern feature for the first contact pad (420) will not be over-resolved, increasing formation accuracy of the first contact pad (420) and thus guaranteeing good electrical transmission performance of the resulting interconnect structure (400).
