    • There is provided an image processor and a method thereof for high-speed compensation for taken-image blurs produced by camera shakes or the like. In the first instance, a motion-detecting area is selected for each of two images taken by an image sensor. When projective data is calculated by means of computing in a predetermined direction pixels of the motion-detecting areas, the motion vector between the two images can be acquired based on the projective data. The image correlativity between the two images is then calculated in the direction that the motion vector designates; and the amount of pixel displacement between the two images is calculated based on the correlativity values acquired by the calculation. Moreover, the area that has been produced by displacing an image output area in a camera-shake compensation area designated in the second frame, by the pixel-displacement amount calculated by a displacement calculator is cut away from the camera-shake compensation area, and is outputted as an image for the image output area of the second frame.

    • A vertical type semiconductor device is provided with an improved construction which greatly decreases the on-resistance without impairing the breakdown voltage thereof. In the fundamental DMOS cells that control a current to constitute the vertical semiconductor device, through-hole cells are arranged along the sides of a cell having a channel. The through-hole cell includes a through-hole extending from the surface of an n.sup.- -type drift region toward an n.sup.+ -type drain region, and also includes an n.sup.+ -type through-hole region that is formed by diffusing impurities from the inner wall of the through-hole which is continuous with the n.sup.+ -type drain region. A breakdown voltage of the element is maintained by the n.sup.- -type drift region between a p-type well region and the n.sup.+ -type through-hole region or the n.sup.+ -type drain region. Given the unique arrangement of the through-hole cells, the JFET resistance component becomes negligibly small between the DMOS cells neighboring along the sides of the cells despite the fact that the cells are finely formed, and a small on-resistance is exhibited.
    • 垂直型半导体器件具有改进的结构,其大大降低导通电阻而不损害其击穿电压。 在控制电流以构成垂直半导体器件的基本DMOS单元中,沿着具有沟道的单元的侧面布置有通孔单元。 通孔单元包括从n型漂移区域的表面向n +型漏极区域延伸的通孔,还包括通过从内部扩散杂质形成的n +型通孔区域 与n +型漏极区连续的通孔的壁。 元件的击穿电压由p型阱区域和n +型通孔区域或n +型漏极区域之间的n型漂移区域维持。 鉴于通孔单元的独特布置,尽管细胞形成细小,但是出现小的导通电阻,但是JFET电阻分量在沿着单元侧面相邻的DMOS单元之间变得可以忽略不计。

    • A semiconductor strain sensor includes a silicon substrate, a strain resistive element and electrodes. The silicon substrate has a deformable portion which is deformed when stress is applied to it. The strain resistive element is formed on the deformable portion and has an at least a first layer and a second layer which form a heterojunction between them. The first layer is doped with impurities so that a two-dimensional carrier gas layer is formed in the second layer near the heterojunction. The two-dimensional carrier gas layer has carriers originating from the impurities. The electrodes electrically contact the two dimensional carrier gas layer. Change of resistance of the strain resistive element in accordance with the stress is detected through the electrodes.
