Abstract: A semiconductor device includes a substrate. An active pattern extends in a first horizontal direction on the substrate. First to third nanosheets are sequentially spaced apart from each other in a vertical direction on the active pattern. A gate electrode extends in a second horizontal direction on the active pattern and surrounds the first to third nanosheets. A source/drain region includes a first layer disposed along side walls and a bottom surface of a source/drain trench and a second layer filling the source/drain trench. The second layer includes a first lower side wall facing a side wall of the first nanosheet and an opposite second lower side wall. A lower surface connects the first and second lower side walls and extends in the first horizontal direction. The first and second lower side walls of the second layer extend to have a constant slope in opposite directions to each other.

Abstract: Proposed is a rubber pad for a steel track. The rubber pad coupled to the steel track formed by connecting a plurality of links and provided with a bushing engaging with a sprocket to allow driving of equipment may include a rubber pad body coupled to an outside of the link and a bushing cover extending from an outer surface of the pad body toward the adjacent pad body to shield the bushing from the outside, wherein a foreign substance discharging groove having the bushing cover inside may be formed in the pad body.

Abstract: A rubber track to prevent occurrence edge-cuts and improve traction force even in the soft ground is disclosed. The rubber track is configured by first lugs which are formed at equal intervals on one side of the inside and the outside in a traveling direction on a surface coming into contact with the ground and have first grooves formed in a width direction; and second lugs which are formed at equal intervals on the other side of the inside and the outside in a traveling direction on a surface coming into contact with the ground and have second grooves formed in the traveling direction.

Abstract: A suspension device for a track loader and a track loader having the same are provided that are capable of releasing the shocks applied to a body and minimizing the pitching of the body generated during the work and driving of the track loader to prevent the body from being damaged, reducing a driver's fatigue, and enhancing the workability and rising comfort of the track loader.

Abstract: An apparatus for controlling tension of a track, and more particularly to an apparatus for preventing a track wheel from separating due to an uneven road surface and obstacles on the road surface by minimizing space between a moving idler and roller when controlling the tension of the track, and for supporting the weight of a machine more safely by maximizing the space between a rear roller and a front roller. To this end, the present invention is characterized by: a track frame structure in which the idler and the front roller move together when controlling the tension of the track; and a damping member for absorbing external shock, wherein the idler is fixed in an idler frame, the front roller is fixed in a roller frame, and the buffer member is positioned between the idler frame and the roller frame.
