摘要： In a power semiconductor device such as an IGBT, a fifth region of n conductivity type is provided. The fifth region is formed in a portion of a second region (drain region) contacting an insulating layer below the gate layer. The fifth region contacts a third region (base region) and has an impurity concentration higher than that of the second region. Therefore, even when a carrier life time is sufficiently short, an electron distribution density can be kept high in the entire fifth region and the second region under the third region (base region) near the fifth region, and the localization of a hole current is moderated (in a case of a p-type base and an n-type drain). As a result, a maximum controllable current is increased, and a wide safe operation area can be obtained.

摘要： A method for reproducing data according to the present invention is adapted for reproducing data recorded in an optical recording disc including a multi-layered body formed by forming a decomposition reaction layer containing noble metal oxide as a primary component and a light absorption layer so as to sandwich a dielectric layer therebetween by irradiating a laser beam onto the optical recording disc and forming a recording mark train including at least one of a recording mark having a length shorter than a resolution limit and a blank region having a length shorter than the resolution limit therein, and is constituted by changing the read power Pr of the laser beam in accordance with a readout linear velocity at which data are to be reproduced from the optical recording disc. According to the thus constituted method for reproducing data, even in the case where the length of a recording mark or the length of a blank region between neighboring recording marks is shorter than the resolution limit, it is possible to record and reproduce a recording mark train including these recording marks and the blank regions. Therefore, this method can be applied to an optical recording medium whose storage capacity is markedly increased.

摘要： Base regions of a second conductivity type are formed and spaced apart from one another in a first major surface of a semiconductor substrate of a first conductivity type which functions as a drain region. Source regions of the first conductivity type are formed in each of the base regions and spaced apart from one another. Gate insulating films are formed on portions of the drain region which are located between adjacent source regions. Gates are formed on the gate insulating films. Source electrodes are formed such that each electrode short-circuits one-base region to the source regions formed in the base region. A first anode region of the second conductivity type is formed on a second major surface of the semiconductor substrate. A second anode region of the second conductivity type is formed on the first anode region. This second anode region is made of polycrystalline silicon of the second conductivity type and has an impurity concentration higher than that of the first anode region. An anode electrode is formed on the second anode region.

摘要： In a current detecting cell of a MOS-type semiconductor device with a current detection function, the area of the contact portions of source regions which contact a current detecting electrode is greater than that of that contact portion of a base region which contacts the current detecting electrode. With this feature, a parasitic resistance does no sharply decrease even if a detected voltage increases, and therefore, current can be detected accurately.
