Abstract: A semiconductor memory device comprises a cell structure and a peripheral circuit structure electrically connected to the cell structure. The peripheral circuit structure comprises an active region, a first gate structure comprising a first gate insulating layer intersecting the active region and in contact with the active region, a second gate structure comprising a second gate insulating layer spaced apart from the first gate structure, and in contact with the active region, and a source/drain region between the first gate structure and the second gate structure. A thickness of the first gate insulating layer is less than a thickness of the second gate insulating layer. The source/drain region comprises a first region adjacent to the first gate structure and a second region adjacent to the second gate structure. A depth of the first region is equal to a depth of the second region.

Abstract: The disclosure purposes to provide an optical coherence tomography (OCT)-based system for diagnosing a high risk lesion such as a vulnerable atheromatous plaque by using an artificial intelligence model through deep learning. A deep learning-based diagnostic method of diagnosing a high risk lesion of a coronary artery includes: acquiring an OCT image of a coronary artery lesion of a patient; extracting a first feature of a thin cap from the OCT image; setting a region of interest included in the OCT image on a basis of the first feature; and determining whether the region of interest includes a high risk lesion.

Abstract: A pickup apparatus includes a plurality of pickers sliding along a first direction and a space adjuster including a plurality of space adjusting plates. Each picker includes a protruding portion combined with a picker body, and each of the space adjusting plates is between a respective pair of adjacent pickers. The protruding portion of each picker contacts sidewalls of adjacent space adjusting plates. At least one of the space adjusting plates moves along a second direction crossing the first direction. A width in the first direction of each space adjusting plate varies along the second direction.
