Abstract:
A method includes etching a first semiconductor fin and a second semiconductor fin to form first recesses. The first and the second semiconductor fins have a first distance. A third semiconductor fin and a fourth semiconductor fin are etched to form second recesses. The third and the fourth semiconductor fins have a second distance equal to or smaller than the first distance. An epitaxy is performed to simultaneously grow first epitaxy semiconductor regions from the first recesses and second epitaxy semiconductor regions from the second recesses. The first epitaxy semiconductor regions are merged with each other, and the second epitaxy semiconductor regions are separated from each other.

Claim (Index 1):
A method comprising:\n forming a first semiconductor fin, a second semiconductor fin, a third semiconductor fin, and a fourth semiconductor fin protruding higher than top surfaces of isolation regions, wherein the first semiconductor fin is close to, and have a first distance from, the second semiconductor fin, and the third semiconductor fin is close to, and have a second distance from, the fourth semiconductor fin, wherein the second distance is equal to or smaller than the first distance; etching the first semiconductor fin and the second semiconductor fin to form first recesses; etching the third semiconductor fin and the fourth semiconductor fin to form second recesses; and performing an epitaxy to simultaneously grow first epitaxy semiconductor regions from the first recesses and second epitaxy semiconductor regions from the second recesses, wherein the first epitaxy semiconductor regions are merged with each other, and the second epitaxy semiconductor regions are separated from each other.
