Abstract:
A first source/drain structure is disposed over a substrate. A second source/drain structure is disposed over the substrate. An isolation structure is disposed between the first source/drain structure and the second source/drain structure. The first source/drain structure and a first sidewall of the isolation structure form a first interface that is substantially linear. The second source/drain structure and a second sidewall of the isolation structure form a second interface that is substantially linear. A first source/drain contact surrounds the first source/drain structure in multiple directions. A second source/drain contact surrounds the second source/drain structure in multiple directions. The isolation structure is disposed between the first source/drain contact and the second source/drain contact.
