Claim:
1. A semiconductor device, comprising: at least one nanowire structure disposed on a semiconductor substrate and extending in a first direction on the semiconductor substrate, wherein each nanowire structure comprises a plurality of nanowires extending along the first direction and arranged in a second direction, the second direction being substantially perpendicular to the first direction, wherein each nanowire is spaced-apart from an immediately adjacent nanowire; a gate structure extending in a third direction over a first region of the nanowire structure, the third direction being substantially perpendicular to both the first direction and the second direction, and the gate structure including a gate electrode; source/drain regions disposed over a second region of the nanowire structure, the second region of the nanowire structure being located on opposing sides of the gate structure, wherein the gate electrode wraps around each of the nanowires, and when viewed in a cross section taken along the third direction each nanowire in the nanowire structure is differently shaped from other nanowires in the nanowire structure, and each nanowire in the nanowire structure has a substantially same cross-sectional area as other nanowires in the nanowire structure.
