Abstract: A semiconductor includes a first semiconductor chip, and a second semiconductor chip provided on the first semiconductor chip. The first semiconductor chip includes a first semiconductor substrate including a first front side and a first back side, and a first back-side bonding layer including a first back-side bonding insulating film, and a first back-side bonding pad, wherein the second semiconductor chip includes a second semiconductor substrate including a second front side that faces the first back side and a second back side, and a second front-side bonding layer including a second front-side bonding insulating film bonded to the first back-side bonding insulating film. A side of the first semiconductor chip includes a plurality of first recesses, which are arranged along a vertical direction, and a second recess, which partially exposes a bottom surface of the second front-side bonding layer between the second front-side bonding layer and the first recesses.

Abstract: Disclosed herein are a radiographic imaging apparatus and a method of controlling the radiographic imaging apparatus. The radiographic imaging apparatus may include an imager configured to image a subject to obtain image data; a real-time processor configured to communicate with the imager and configured to obtain a real-time processing authority and perform real-time image processing on the image data; and a non-real-time processor configured to communicate with the imager and configured to perform non-real-time image processing on the image data, and in response to a failure occurring in the real-time processor, obtain the real-time processing authority and perform the real-time image processing on the image data.

Abstract: A radiographic system includes a photographic unit; an operating panel including a button configured to be pressed to indicate that a movement direction of the photographic unit is to be limited to a specific movement direction; a measurement unit provided between the operating panel and the photographic unit and configured to measure a magnitude and a direction of an external force applied to the operating panel; and a drive unit configured to move the photographic unit only in the specific movement direction based on the magnitude and the direction of the external force measured by the measurement unit in response to the button being pressed.
