Abstract:
A semiconductor device includes a layer having a semiconductive material. The layer includes an outwardly-protruding fin structure. An isolation structure is disposed over the layer but not over the fin structure. A first spacer and a second spacer are each disposed over the isolation structure and on sidewalls of the fin structure. The first spacer is disposed on a first sidewall of the fin structure. The second spacer is disposed on a second sidewall of the fin structure opposite the first sidewall. The second spacer is substantially taller than the first spacer. An epi-layer is grown on the fin structure. The epi-layer protrudes laterally. A lateral protrusion of the epi-layer is asymmetrical with respect to the first side and the second side.

Claim (Index 21):
A semiconductor device, comprising:\n a layer that includes a semiconductive material, the layer including a first fin structure and a second fin structure; an isolation structure disposed over the layer; a first spacer and a second spacer each disposed over the isolation structure and on opposite sidewalls of the first fin structure, wherein the first spacer is disposed on a first sidewall of the first fin structure, wherein the second spacer is disposed on a second sidewall of the first fin structure opposite the first sidewall, and wherein the second spacer is taller than the first spacer; a first epi-layer grown on the first fin structure, the first epi-layer protruding laterally outward toward the first spacer, wherein a first edge of the first epi-layer toward the first spacer is more rounded than a second edge of the first epi-layer toward the second spacer, and wherein the first edge protrudes laterally beyond an outermost edge of the first spacer; a second epi-layer grown on the second fin structure, the second epi-layer protruding laterally opposite the first epi-layer, wherein the second epi-layer does not merge into the first epi-layer; a first metal contact disposed on the first epi-layer; and a second metal contact disposed on the second epi-layer, wherein the first and second metal contacts are electrically isolated from each other.
