    Abstract: Disclosed are mask layout correction methods and a method for fabricating semiconductor devices. The mask layout correction method comprises performing a first optical proximity correction on an initial pattern layout. The step of performing the first optical proximity correction includes providing a target pattern of the initial pattern layout with control points based on a first model, obtaining a predicted contour of the initial pattern layout by performing a simulation, and obtaining an error between the target pattern and the predicted contour from the control points. The control points include first control points on an edge of the target pattern and second control points in an inside of the target pattern. The step of obtaining the error includes acquiring first error values from the first control points, providing weights to the first error values, and acquiring second error values from the second control points.

    Abstract: A method for manufacturing a semiconductor device includes obtaining a design layout for a target layer of an optical proximity correction process, the design layout including a first block and a second block being a repetition block of the first block, dividing the design layout into a plurality of patches, performing the optical proximity correction process on the patches of the first block, applying corrected patches of the first block to the patches of the second block, respectively, forming a correction layout by performing the optical proximity correction process on boundary patches of the second block, fabricating a photomask corresponding to the correction layout, and forming patterns on a substrate corresponding to the photomask. Each of the patches is a standard unit on which the optical proximity correction process is performed.

    Abstract: A method of manufacturing a semiconductor device is disclosed. The method includes generating a first virtual layout by placing and routing standard cells using a virtual netlist, searching first duplicate pattern regions in the first virtual layout and choosing one of them as a first representative pattern region, performing an OPC operation on the first representative pattern region to obtain a first OPC result, generating an actual layout by placing and routing standard cells using an actual netlist, performing an OPC operation on the actual layout, and forming a photoresist pattern on a substrate using a photomask manufactured based on the actual layout, to which the OPC operation is applied.

    Abstract: A semiconductor device includes a substrate including an active region extending in a first direction, a gate structure extending in a second direction intersecting the active region on the substrate and including a gate dielectric layer and a gate electrode, channel layers spaced apart from each other in a third direction perpendicular to an upper surface of the substrate on the active region and surrounded by the gate structure, a lateral structure disposed on internal side surfaces of the gate dielectric layer and contacting the gate dielectric layer and the gate electrode, and source/drain regions disposed in regions in which the active region is recessed on opposite sides of the gate structure, and connected to the channel layers. A level of lower surfaces of the lateral structures is higher than a level of a lower surface of the gate electrode.
