Abstract:
A method includes forming a crown structure over a substrate; forming fins in the crown structure; forming an intra-device isolation region between the fins and forming inter-device isolation regions on opposing sides of the crown structure; forming a gate structure over the fins; forming a dielectric layer that extends continuously over the inter-device isolation regions, the fins and the intra-device isolation region; performing an etching process to reduce a thickness of the dielectric layer, where after the etching process, upper surfaces of the inter-device isolation regions and upper surfaces of the fins are exposed while an upper surface of the intra-device isolation region is covered by a remaining portion of the dielectric layer; and forming an epitaxial structure over the exposed upper surfaces of the fins, where after the epitaxial structure is formed, there is a void between the epitaxial structure and the intra-device isolation region.

Claim (Index 1):
A semiconductor device comprising:\n a plurality of inter-device isolation structures; and a crown active region disposed between the plurality of inter-device isolation structures, wherein the crown active region comprises:\n a first semiconductor fin and a second semiconductor fin immediately adjacent to the first semiconductor fin; \n an intra-device isolation structure disposed between the first semiconductor fin and the second semiconductor fin; \n an epitaxy structure comprising a first portion on the first semiconductor fin and a second portion on the second semiconductor fin, wherein a bottommost surface of the epitaxial structure is below a top surface of the intra-device isolation structure, wherein an air gap is between the intra-device isolation structure and the epitaxy structure; and \n a dielectric layer on the intra-device isolation structure, the dielectric layer extending continuously along the top surface of the intra-device isolation structure from a first sidewall of the first portion of the epitaxy structure to a second sidewall of the second portion of the epitaxy structure facing the first sidewall.
