    摘要: The present invention relates to a contact structure not only for a semiconductor device having a hetero-junction bipolar transistor or a hetero-insulated gate field effect transistor but also for semiconductor devices at large. In a semiconductor layer of a polycrystalline or amorphous undoped III-V compound semiconductor or an alloy thereof, a through hole is formed for contact. The size of the through hole is set to permit exposure of at least part of a first conductor layer and a dielectric layer, such as an Si compound, present around the first conductor layer, and a second conductor layer is formed within the through hole so as to contact the first conductor layer. Since the semiconductor layer can be subjected to a selective dry etching for the dielectric layer, the dielectric layer is not etched at the time of forming the above through hole in the semiconductor layer. As a result an electric short-circuit of the second conductor layer with a single crystal semiconductor layer which underlies the dielectric layer can be prevented.

    摘要: A blood vessel ultrasonic image measuring method capable of facilitating the positioning of an ultrasonic probe and acquiring sufficient positioning accuracy. Because of inclusion of an around-X-axis positioning step of causing a multiaxis driving device to position an ultrasonic probe such that distances from respective ultrasonic array probes to the center of a blood vessel are equalized, and an X-axis direction positioning step and an around-Z-axis positioning step of causing the multiaxis driving device to position the ultrasonic probe such that the image of the blood vessel is positioned at the center portion in the width direction of the first short axis image display area and the second short axis image display area, the positioning may be performed by using the positions in the longitudinal direction of the ultrasonic array probes relative to the blood vessel or the distances of the ultrasonic array probes to the blood vessel.

    摘要: Provided is a display device in which design properties have been improved by eliminating the flickering when the display level changes. A microcomputer (5) causes light emission of first LEDs (23 and 24) which are the first and second ones counting from the right end among the emitting first LEDs (21 to 24), with decreasing brightness towards the right end. Furthermore, the microcomputer (5) causes light emission of second LEDs from a second LED (77) which is disposed at the right end of the second LEDs (71 to 77), to a second LED (73) which is disposed at a position overlapped with the first LEDs (23 and 24) that emit light with decreasing brightness towards the right end, and also causes light emission of second LEDs (73 and 74), which are the first and second ones counting from the left end among the emitting second LEDs (73 to 77), with decreasing brightness towards the left end.

    摘要: External electrodes are provided on a bottom surface of a laminate, and are connected to both ends of a main line and both ends of a sub-line, respectively. A warpage prevention conductor is provided on an insulating material layer that is provided on a top surface side of the laminate with respect to insulating material layers to which the main line is provided and with respect to insulating material layers to which the sub-line is provided. The warpage prevention conductor overlaps with the external electrodes when seen from a z-axis direction in a plan view. A conductor layer that is not connected to the main line or the sub-line is not provided on any of the insulating material layers provided on a bottom surface side of the laminate with respect to the insulating material layer on which the warpage prevention conductor is provided.
