Abstract

A structure and a formation method of a semiconductor device are provided. The method includes forming a first source/drain structure and a second source/drain structure over a semiconductor substrate. The method also includes forming a dielectric layer over the first source/drain structure and the second source/drain structure and forming a conductive contact on the first source/drain structure. The method further includes forming a first conductive via over the conductive contact, and the first conductive via is misaligned with the first source/drain structure. In addition, the method includes forming a second conductive via directly above the second source/drain structure, and the second conductive via is longer than the first conductive via.
