    Abstract: A method of fabricating a semiconductor device includes performing an optical proximity correction (OPC) operation on a layout and forming a photoresist pattern on a substrate using a photomask that is manufactured with the layout corrected by the OPC operation. The OPC operation includes sectioning the layout into a low-level patch and a high-level patch, performing a first OPC operation on the low-level patch, the first OPC operation including generating a first boundary correction pattern of a curvilinear shape on a boundary between the low-level patch and the high-level patch, performing a second OPC operation on the high-level patch, the second OPC operation including a second boundary correction pattern of a curvilinear shape on the boundary, and conforming the first boundary correction pattern and the second boundary correction pattern to each other to generate a conformed boundary correction pattern of a curvilinear shape.

    Abstract: A method of fabricating a semiconductor device is disclosed. The method includes performing an optical proximity correction (OPC) on a design pattern of a layout and forming a photoresist pattern on a substrate using a photomask manufacture based the corrected layout. The performing of the OPC includes analyzing a cell hierarchy to choose a representative cell in the layout, dividing the design pattern in the representative cell into a plurality of segments including first segments, choosing a first unique segment, which represents the first segments, from the plurality of segments, generating a first correction bias of the first unique segment, applying the first correction bias to all of the first segments to generate a correction pattern, and applying a correction result of the representative cell to other cells that are included in the layout and are of a same type as the representative cell.

    Abstract: A photomask fabrication method comprising performing an optical proximity correction (OPC) on a design pattern to generate a correction pattern, and manufacturing the photomask having the correction pattern. The step of performing the OPC includes dividing the design pattern into a plurality of segments, producing a hash value for each of the plurality of segments, and generating the correction pattern by applying a first correction bias to ones of the plurality of segments having a same hash value, wherein at least two of the plurality of segments have the same hash value. The step of producing the hash value includes generating a key segment in a target segment, creating a query region around the key segment, and producing the hash value for the target segment based on a pattern image in the query region.

    Abstract: Disclosed are reticle fabrication methods and semiconductor device fabrication methods. The reticle fabrication method includes performing a photolithography process on a test substrate using a first reticle having first patterns, measuring the test substrate to obtain measured images, designing a second reticle having second patterns, redesigning the second reticle based on a margin of the photolithography process, and manufacturing the redesigned second reticle. Redesigning the second reticle includes obtaining sample images from the measured images when the first patterns are the same as the second patterns, obtaining contour images that have contours of sample patterns in the sample images, overlapping the contours to obtain a contour overlay value, and comparing the contour overlay value with a reference value to determine defects of the second patterns.

    Abstract: A method of operating a data processing system includes transmitting process information indicating that a first process is classified as a critical process or a non-critical process to a kernel area, wherein the process information is generated in an application area, and the application area and the kernel area define a host. When the first process is classified as a critical process based on the process information, a first fastpath write signal is provided, using the kernel area, to a memory system to perform a fastpath write operation of first data for performing the first process. When the first process is classified as a non-critical process, a first slowpath write signal is provided to the memory system to perform a slowpath write operation of the first data. The fastpath write operation has a higher write speed than the slowpath write operation.
