The capacitor structure includes a lower electrode, an upper electrode, and a capacitor dielectric film which is interposed between the lower electrode and the upper electrode, wherein the lower electrode includes an electrode film including a first metal element, and a doping oxide film including an oxide of the first metal element between the electrode film and the capacitor dielectric film, and the doping oxide film further includes a second metal element including at least one of Group 5 to Group 11 and Group 15 metal elements, and an impurity element including at least one of silicon (Si), aluminum (Al), zirconium (Zr) and hafnium (Hf).

Abstract: A highly durable electrolyte membrane using cerium oxide supported with an alloy catalyst that is a hydrogen-oxygen reaction catalyst for improving chemical durability of an electrolyte membrane increases durability of a membrane-electrode assembly including the same and decreases the manufacturing cost thereof.

Abstract: Disclosed is an apparatus for improving construction precision based on extended reality (XR). At least one piece of XR content related to a construction target positioned in front inside a construction site is displayed on a display unit. When a construction position of a construction object included in the construction target is determined, the XR content including the design information of the construction object at the construction position is displayed on the display unit.

Abstract: A dual port memory device converts an address and a control signal, which are inputted via a first port and conform to a first type memory interface, into an address and a control signal which conform to a second type memory interface, to access a memory array. The dual port memory device accesses a memory array based on an address and a control signal which are inputted via a second port and conform to the second type memory interface. The dual port memory device accesses a memory array according to the first type memory interface or the second type memory interface in response to a selecting signal. Therefore, the dual port memory device can be coupled to a processor with a first interface (e.g., PSRAM or SRAM interface) and a processor with a second interface (e.g., SDRAM interface).
