    摘要: A semiconductor device includes a substrate including a first active region and a second active region, the first active region having a conductivity type that is different than a conductivity type of the second active region, and the first active region being spaced apart from the second active region in a first direction, gate electrodes extending in the first direction, the gate electrodes intersecting the first active region and the second active region, a first shallow isolation pattern disposed in an upper portion of the first active region, the first shallow isolation pattern extending in the first direction, and a deep isolation pattern disposed in an upper portion of the second active region, the deep isolation pattern extending in the first direction, and the deep isolation pattern dividing the second active region into a first region and a second region.

    摘要: A method of manufacturing a semiconductor device may include forming active patterns, forming a polygonal mask pattern having a first width and a second width on the active patterns, forming an active region by executing a first etching process using the mask pattern, forming a first cutting mask for removing a first corner rounding in which a width of the active region is the first width, removing the first corner rounding by executing a second etching process using the first cutting mask, forming a second cutting mask for removing a second corner rounding in which the width of the active region is changed from the first width to the second width, and executing a third etching process using the second cutting mask.
