Abstract: Provided are semiconductor devices including device isolation layers. The semiconductor device includes a substrate having a cell region and a core/peripheral region, a first active region in the cell region of the substrate, a first device isolation layer that defines the first active region, a second active region in the core/peripheral region of the substrate; and a second device isolation layer that defines the second active region. A height from a lower surface of the substrate to an upper end of the first device isolation layer in a first direction that is perpendicular to the lower surface of the substrate is less than or equal to a height from the lower surface of the substrate to an upper end of the first active region in the first direction.
