Abstract:
1. A fin field-effect transistor (FinFET) comprising: a substrate having at least two initial fin structures thereon, the initial fin structures each including opposing sidewalls having a top portion and a bottom portion and having a first shape; an epitaxially grown fin structure disposed between the two initial fin structures, the epitaxially grown fin structure including angled opposing sidewalls having a top portion and a bottom portion and having a second shape which is different from the first shape of the initial fin structure opposing sidewalls; and a pair of spacers which are disposed between the initial fin structures and which are disposed about respective sidewalls of the epitaxially grown fin structure; wherein each spacer of the pair abuts a sidewall of the initial fin structures and abuts a corresponding sidewall of the epitaxially grown fin structure and extends continuously between the sidewall of the initial fin structures and the corresponding sidewall of the epitaxially grown fin structure.
