Abstract: A semiconductor device has an active region in which a plurality of unit cells are regularly arranged, each of the unit cells including: a channel region having a first conductivity type and formed over a front surface of a semiconductor substrate; a source region having a second conductivity type different from the first conductivity type and formed over the front surface of the semiconductor substrate in such a manner as to be in contact with the channel region; and a JFET region having the second conductivity type and is formed over the front surface of the semiconductor substrate on the opposite side of the channel region from the source region in such a manner as to be in contact with the channel region. The channel region is comprised of a first channel region and a second channel region higher than the first channel region in impurity concentration, over the front surface of the semiconductor substrate.

Abstract: A sensing data correction system corrects sensing data acquired from a glove-type wearable sensor in which a film-like pressure sensor is incorporated into a fingertip, and includes a data correction unit for correcting the sensing data. Three coordinate axis directions in a three-dimensional orthogonal coordinate system are assumed to be a vertical direction, a longitudinal direction of the pressure sensor, and a width direction of the pressure sensor, and the pressure sensor is obtained by laminating one flexible printed circuit, one sheet-like pressure sensitive element, and one protective film in the vertical direction. An upper surface of the flexible printed circuit and a lower surface of the pressure sensitive element are bonded and fixed to each other, and an upper surface of the pressure sensitive element and a lower surface of the protective film are bonded and fixed to each other. The data correction unit executes sensing data correction processing.

Abstract: A trench groove is formed and a silicon oxide film is buried in the periphery of a channel region of (0001) surface 4h-SiC semiconductor element. The oxide film in the trench groove is defined in such a planar layout that a tensile strain is applied along the direction of the c-axis and a compressive strain is applied along two or more of axes on a plane perpendicular to the c-axis. For example, trench grooves buried with an oxide film may be configured to such a layout that they are in a trigonal shape surrounding the channel, or are arranged symmetrically with respect to the channel as a center when arranged discretely.

Abstract: A technique that can emit a sensor signal that accurately reflects only the pressure to be truly detected in a glove-type wearable sensor in which a film-like pressure sensor is incorporated into a fingertip of a thin work glove is disclosed. In a film-like pressure sensor incorporated into a fingertip of a glove-type wearable sensor, three coordinate axis directions in a three-dimensional orthogonal coordinate system are assumed to be a vertical direction, a longitudinal direction of the pressure sensor, and a width direction of the pressure sensor, at least one or more flexible printed circuits and one sheet-like pressure sensitive element are laminated in the vertical direction, and only the pressure applied to the fingertip of a wearer after wearing the wearable sensor is detected.

Abstract: An operation motion is accurately determined in an operational information management system. The system includes a motion verification portion that combines and verifies plurality of pieces of sensor information and recognizes a specific body motion, a signal determination portion that determines whether an operation content of an operator is correctly performed based on the body motion recognized by the motion verification portion, and a report portion that reports a determine result of the signal determination portion.
