Abstract: A semiconductor structure, including a plurality of connection patterns disposed on the substrate, and a merged pattern disposed between adjacent two of the connection patterns, wherein the merged pattern includes a first outer line, a central line and a second outer line sequentially arranged along a first direction and connected with each other, and an end surface of the first outer line, an end surface of the central line and an end surface of the second outer line are misaligned along the first direction.

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).

Abstract: A semiconductor structure includes a substrate, a first dielectric layer on the substrate, a second dielectric layer on the first dielectric layer, and an interconnection structure on the second dielectric layer. The interconnection structure includes at least two lateral extending portions on the second dielectric layer, and a U-shaped portion through the second dielectric layer and a portion of the first dielectric layer and connected between adjacent ends of the two lateral extending portions.

Abstract: A contact structure, contact pad layout and structure, mask combination and manufacturing method thereof is provided in the present invention. Through the connection of tops of at least two contact plugs in the boundary of core region, an integrated contact with larger cross-sectional area is formed in the boundary of core region. Accordingly, the process of forming electronic components on the contact structure in the boundary of core region may be provided with sufficient process window to increase the size of electronic components in the boundary, lower contact resistance, and the electronic component with increased size in the boundary buffer the density difference of circuit patterns between the core region and the peripheral region, thereby improving optical proximity effect and ensuring the uniformity of electronic components on the contact plugs inside the boundary of core region, and avoiding the collapse of electronic components on the contact plug in the boundary.
