Abstract: A semiconductor device may include a first film and a second film defining parts of a trench, a plug conductive film, a via, and a wiring in the trench. The trench may include a second sub-trench having a second width below a first sub-trench having a first width. The plug conductive film may extend from a first side of the first film to penetrate a bottom face of the trench. An uppermost face of the plug conducive film may be in the trench. The via may include an insulating liner between the plug conductive film and the first film. The uppermost face of the plug conductive film and at least a part of a side wall of the plug conductive film may be in contact with the wiring. An upper face of the insulating liner may be exposed by a bottom face of the second sub-trench.

Abstract: A pop-up monitor with an obstacle sensing function is provided. The pop-up monitor includes a body housing and a monitor frame which is installed to move in a vertical direction with respect to the body housing. The pop-up monitor includes a driving unit, a sensor, and a controller. The driving unit includes a motor, a rotational shaft, and a gear set which transfers a rotational motion of the motor to the rotational shaft. The sensor outputs a sensing signal for whether the rotational shaft rotates. The controller outputs a control signal for a rotational direction of the motor according to the sensing signal and state information regarding whether the motor rotates.

Abstract: A gear structure is configured to support vertical motion of an electric pop-up monitor. More specifically, a double rack gear structure is configured to support a pop-up monitor. The rack gear structure includes an outer gear and an inner gear. The outer gear is coupled at a side of the monitor frame to operate integrally with the monitor frame, and enables the vertical motion of the monitor frame with an ascending or descending motion. The inner gear is received inside the outer gear. The inner gear performs an ascending or descending motion simultaneously with the outer gear, and supports forward and rearward or right and left shaking, which occurs in the outer gear, by maximizing a portion overlapping with the outer gear when the outer gear has ascended to the maximum.
