    摘要: First and second gate insulating films are formed so as to cover at least the upper corner of first and second fin-shaped semiconductor regions. The radius of curvature r1′ of the upper corner of the first fin-shaped semiconductor region located outside the first gate insulating film is greater than the radius of curvature r1 of the upper corner of the first fin-shaped semiconductor region located under the first gate insulating film and is less than or equal to 2×r1. The radius of curvature r2′ of the upper corner of the second fin-shaped semiconductor region located outside the second gate insulating film is greater than the radius of curvature r2 of the upper corner of the second fin-shaped semiconductor region located under the second gate insulating film and is less than or equal to 2×r2.
