Abstract:
1. A method of manufacturing a semiconductor device, the method comprising: forming device isolation patterns on a substrate; forming an active fin on the substrate, such that the active fin protrudes from the substrate in a direction perpendicular to an upper surface of the substrate; oxidizing a portion of the active fin to form an insulating pattern between the active fin and the substrate, such that the insulating pattern electrically insulates the active fin from the substrate; forming a first gate pattern on the substrate, wherein the first gate pattern crosses the active fin; exposing the substrate on both sides of the first gate pattern; and forming source/drain regions on the exposed substrate, such that the source/drain regions are arranged on both sides of the first gate pattern, and are connected to the substrate, wherein the insulating pattern is connected to the device isolation patterns which are adjacent to each other and between which the insulating pattern is positioned.
