Abstract:
Systems and methods related to a structured illumination (SI)-based inspection apparatus are described. The SI-based inspection apparatus may be capable of accurately inspecting an inspection object in real time with high resolution, while reducing the loss of light. Also described are an inspection method, and a semiconductor device fabrication method including the SI-based inspection method. The inspection apparatus may include a light source configured to generate and output a light beam, a phase shifting grating (PSG) configured to convert the light beam from the light source into the SI, a beam splitter configured to cause the SI to be incident on an inspection object and output a reflected beam from the inspection object, a stage capable of moving the inspection object and on which the inspection object is arranged, and a time-delayed integration (TDI) camera configured to capture images of the inspection object by detecting the reflected beam.
Abstract:
A three-dimensional semiconductor memory device including a substrate including a first connection region, a second connection region, and a cell array region disposed between the first and second connection regions. The memory device further includes an electrode structure including a plurality of electrodes vertically stacked on the substrate, wherein each of the electrodes has a pad exposed on the first connection region, and a dummy electrode structure disposed adjacent to the electrode structure and including a plurality of dummy electrodes vertically stacked on the substrate. Each dummy electrode has a dummy pad exposed on the second connection region. The electrode structure includes a first stair structure and a second stair structure which each includes the pads of the electrodes exposed on the first connection region. The first stair structure extends along a first direction, and the second stair structure extends along a second direction that crosses the first direction.
Abstract:
A memory card includes first and second groups of terminals, at least one controller, and first and second nonvolatile memories. The first group of terminals are adjacent to an edge at an insertion side of a substrate and include a first power terminal to provide a first voltage. The second group of terminals is spaced farther apart from the edge at the insertion side than the first group of terminals and includes a second power terminal to provide a second voltage. The at least one memory controller is connected to the first and second groups of terminals, and the first and second nonvolatile memories are independently connected to the at least one controller. The at least one controller simultaneously accesses the first nonvolatile memory and the second nonvolatile memory when the first group of terminals and the second group of terminals are connected to an external host.
