Abstract
Embodiments of present invention provide a transistor structure. The transistor structure includes a first vertical fin of a first vertical transistor, the first vertical fin having a first and a second sidewall and a first and a second vertical end; a first bottom source/drain (S/D) region underneath the first vertical fin, wherein the first bottom S/D region having an edge that vertically aligns with the first vertical end of the first vertical fin; and a first gate stack surrounding the first vertical fin, wherein the first bottom S/D region horizontally extends beyond the first vertical fin, except at the edge of the first bottom S/D region that vertically aligns with the first vertical end of the first vertical fin, to have at least a portion vertically underneath the first gate stack. A method of manufacturing the transistor structure is also provided.
