摘要： A vertical MOSFET, which can control AC current flowing through a device only by the gate voltage, is obtained. On an n.sup.+ silicon layer is formed an n.sup.- silicon layer. Within the n.sup.- silicon layer is formed a p-body region. Within the p-body region is formed an n.sup.+ source region. On top of a substrate are formed a source electrode in contact only with the source region and a base electrode in contact only with the p-body region. The source electrode and the base electrode are connected to each other through a resistance at the outside. On a channel region is formed a gate electrode through a gate oxide film (insulating film). When the above semiconductor device is in the reverse bias conduction, the exciting current is controlled only by the gate voltage by setting the current flowing from a source terminal through the resistance to the base electrode, the p-body region and the n.sup.- silicon layer to be negligibly small as compared with the current flowing from the source terminal through the source electrode to the n.sup.+ source region, the channel region and the n.sup.- silicon layer.

摘要： A manufacturing method of a vertical DMOSFET having a concave channel structure, which does not permit the introduction of defects or contaminant into the channel part and which can make the shape of the groove uniform, is disclosed. On a surface of a (100)-oriented n.sup.- -on-n.sup.+ epitaxial wafer is formed an initial groove by chemical dry etching. The grooved surface is then oxidized by LOCOS technique to form a LOCOS oxide film, whereby the concave structure is formed on the epitaxial wafer. The concave width is set to be at least twice the concave depth, and the sidewall angle is set to be approximately 50.degree. to make the sidewall plane (111) of high channel mobility plane. Following this process, p-type and n-type impurities are diffused from the main surface using the LOCOS oxide film as a double diffusion mask to form a body region and a source region.

摘要： 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.

摘要： 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.

摘要： 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.
