Abstract:
A manufacturing process and device are provided in which a first opening in formed within a substrate. The first opening is reshaped into a second opening using a second etching process. The second etching process is performed with a radical etch in which neutral ions are utilized. As such, substrate push is reduced.

Claim (Index 8):
A semiconductor device comprising:\n a first gate stack adjacent to a second gate stack located in a first region of a substrate, the first gate stack being separated from the second gate stack by a first distance of between about 20 nm and about 50 nm; a third gate stack adjacent to a fourth gate stack located in a second region of the substrate, the third gate stack being separated from the fourth gate stack by a second distance of between about 100 nm and about 400 nm; a first epitaxial region between the first gate stack and the second gate stack, the first epitaxial region extending into a first semiconductor fin of the substrate a third distance; and a second epitaxial region between the third gate stack and the fourth gate stack, the second epitaxial region extending into a second semiconductor fin of the substrate a fourth distance different from the third distance, wherein a difference between the third distance and the fourth distance is between about \u22123 nm and about 3 nm.
