Abstract: Provided is an aerogel blanket and a method for producing the same, wherein a catalyzed sol is sufficiently and uniformly impregnated into a blanket in an impregnation tank, and the catalyzed sol is allowed to stay in the impregnation tank for a specific time to control fluidity while achieving a viscosity at which the catalyzed sol can be easily introduced into the blanket, thereby forming a uniform aerogel in the blanket. As a result, the uniformity of pore structure and thermal insulation performance of an aerogel blanket are improved, the loss of raw materials is reduced through the impregnation process, the occurrence of process problems is reduced, and the generation of dust is reduced.

Abstract: The inventive concept provides a substrate treating apparatus. The substrate treating apparatus includes a support unit configured to support a substrate; and a cleaning unit configured to clean a bottom surface of the substrate supported on the support unit, and wherein the cleaning unit comprises: a body; and a protrusion formed to be upwardly protruding from the body, and the protrusion is positioned to be spaced apart from the bottom surface.

Abstract: Provided is an aerogel blanket and a method for producing the same, wherein a catalyzed sol I sufficiently and uniformly impregnated into a blanket in an impregnation tank, and the catalyzed sol is allowed to stay in the impregnation tank for a specific time to control fluidity while achieving a viscosity at which the catalyzed sol can be easily introduced into the blanket, thereby forming a uniform aerogel in the blanket. As a result, the uniformity of pore structure and thermal insulation performance of an aerogel blanket are improved, the loss of raw materials is reduced through the impregnation process, the occurrence of process problems is reduced, and the generation of dust is reduced.

Abstract: Semiconductor device and method for fabricating the same are provided. The semiconductor device comprises a first metal wiring line, a chip pad which is electrically connected with the first metal wiring line and has a first width, a passivation layer which encloses the chip pad and includes a contact hole, a first barrier pattern formed on a side wall of the contact hole and a top surface of the passivation layer, a contact filling the contact hole on the first barrier pattern, and a bump, which is formed of the same material as the contact, has a second width which is smaller than the first width, and is overlaid with the first metal wiring line and the chip pad, the bump being entirely overlapped with the chip pad.

Abstract: Disclosed herein is a method of recording and reproducing surveillance images in a Digital Video Recorder (DVR). In one embodiment of the present invention, a recording speed such as a frame rate for surveillance images are controlled according to extent of motion of subjects in the surveillance detected through prediction between neighboring frames, and information about the controlled frame rates and information about time at which the frame rate is used may be managed and recorded in an associated manner. In another embodiment of the present invention, based on information about frame rates managed in associated with information about time at which the frame rate is used, specific frames from surveillance images on a recording medium are selectively reproduced, and a period in which frames are recorded at a frame rate higher than a specific rate may be selected and reproduced.
