Abstract
A multi-gate finFET structure and formation thereof. The multi-gate finFET structure has a first gate structure that includes an inner side and an outer side. Adjacent to the first gate structure is a second gate structure. The inner side of the first gate structure faces, at least in part, the second gate structure. A stress-inducing material fills a fin cut trench that is adjacent to the outer side of the first gate structure. An epitaxial semiconductor layer fills, at least in part, an area between the first gate structure and the second gate structure.
