Claim:
1. A semiconductor device, comprising: a substrate comprising first and second regions; a first fin-type pattern and a second fin-type pattern formed in the first region, protruding from the substrate, and extending in a first direction; a first source/drain on the first fin-type pattern, the first source/drain having a cross section in a second direction intersecting the first direction that defines a first convex polygonal shape; a second source/drain on the second fin-type pattern, the second source/drain having a cross section in the second direction that defines a second convex polygonal shape that is the same as the first convex polygonal shape; a third fin-type pattern and a fourth fin-type pattern formed in the second region, protruding from the substrate, and extending in a third direction; a third source/drain on the third fin-type pattern, the third source/drain having a cross section in a fourth direction intersecting the third direction that defines a third convex polygonal shape; and a fourth source/drain on the fourth fin-type pattern, the fourth source/drain having a cross section in the fourth direction that defines a fourth convex polygonal shape that is different than the third convex polygonal shape.
