摘要： The present invention relates to a diode, and has an object to simultaneously implement a high di/dt capability, a low reverse recovery loss and a low forward voltage and to suppress generation of voltage oscillation. In order to achieve the above-mentioned object, life time killers are selectively introduced into a semiconductor substrate (20) comprising a P layer (1), an N− layer (21) and an N+ layer (3). A density of the introduced life time killers is the highest in a first region (6) adjacent to the P layer (1), and is the second highest in a second region (7) in the N− layer (21). The life time killers are not introduced into a third region (2). Accordingly, a life time in the N− layer (21) is expressed by the first region (6)

摘要： An object is to provide a semiconductor device which is free from such voltage oscillation as may cause malfunction of peripheral equipment. In a semiconductor device having a pin structure, the impurity concentration gradient in an n+ layer (103) serving as a buffer layer is set equal to or less than 2×1018cm−4. Then, when a reverse bias voltage is applied and a depletion layer reaches the n+ layer (103), the expansion of the depletion layer is prevented from rapidly stopping and the voltage oscillation can be suppressed.

摘要： The present invention relates to a reverse conducting thyristor device. It aims at preventing heat generated by power loss from filling end field protective rubber and at simplifying a sheath storing a semiconductor substrate. In a reverse conducting thyristor device according to this invention, a self-extinguishing thyristor region is arranged on an inner region of the semiconductor substrate, a reverse conducting diode region whose outer periphery is completely enclosed with an isolation region is arranged on its outer region by at least one, and an external takeout gate electrode region is further arranged on the outermost peripheral region of the semiconductor substrate on the outer part thereof. Thus, a gate electrode provided on a surface of a gate part layer of the self-extinguishing thyristor region is connected with an external takeout gate electrode formed along the outermost periphery of the substrate through a gate wiring pattern formed on a surface of a connecting region.

A phosphorylation-inhibiting and/or dephosphorylating agent, which has an effect of inhibiting the phosphorylation at least at one of the phosphorylation sites of PTEN protein selected from the group consisting of T382, T383 and S380 and/or an effect of dephosphorylating the same, is prepared. Alternatively, a phosphorylation-inhibiting or dephosphorylating agent for PTEN is screened by a method comprising a step for confirming an ability of a test substance to inhibit the phosphorylation at least at one of the phosphorylation sites of PTEN protein selected from the group consisting of T382, T383 and S380 or a dephosphorylation ability thereof. Then, a substance having an effect opposite to the inhibition of PTEN phosphorylation or dephosphorylation thereof, e.g., an antibody against the phosphorylation-inhibiting or dephosphorylating agent for PTEN obtained above, is also obtained.
