Title: Insulated-gate type thyristor
Inventor: IWAMURO NORIYUKI
IPC: H01L29/745
Filed: 1996-03-25
Abstract: PROBLEM TO BE SOLVED: To enhance the turn-off strength of an emitter-switched thyristor(EST) and to enhance the trade-off characteristics between the on-state voltage and the breakdown strength of the thyristor. SOLUTION: The upper parts of the surfaces of a p-type second region 6 and an emitter region 8 are covered with an insulating film 19, and one part of the region 6 is brought into contact with a p-type first region 4 under a gate electrode 10. Whereupon, as a potential in the region 8 becomes roughly equipotential with that in an n-type source region 7, a potential in the region 6 is made to rise by a hole current injected in the region 6 through a p-type emitter layer 1, and an emitter-switched thyristor is rapidly transferred from an IGBT mode to a thyristor mode.  In particular, an inversion layer at the turn-on time of a gate is short and a resistance is low in the part, which comes into contact with the region 4, of the region 6 and as the part does not come into contact with an n-type base layer 3, electrons from the region 7 flow effectively to the region 8 and the on-state voltage of the thyristor is reduced. At the turn-off time of the thyristor, the recovery of a p-n junction under the region 8 becomes even, the breakdown strength of the thyristor is enhanced and at the same time, the turn-off time of the thyristor is shortened.

Abstract: PURPOSE:To improve the durability and reliability of the title iron, by a method wherein a heat-resisting synthetic resin-made support for supporting an iron main body is fixed on the upper surface side of a stand, and a cord-winding device is fixed on a cover body with which the lower surface side of the stand is covered, and a vent hole is formed between the cord-winding device and the cover body. CONSTITUTION:An iron main body 4 slides down on rollers 14a, 14b mounted on a support 7 which inclines downward in the rear direction thereof, and an electric current-supplying pin 3 is connected to electrodes 9, and thus the iron main body 4 is heated. Although its heat is applied to a stand 6 through the ironing surface of a base 1 placed almost with the bottom up, by radiation and heat transmission, its radiant heat is prevented by the support 7 and its transmitting heat is prevented by the effect of space 12. The radiant heat from the support 7 is diffused by a heat-equalizing board 13 with good heat conductivity which is located in the space 12, and since cool air flows into the stand 6 through a vent hole 17 formed between a cover body 16 and a cord-winding device 15, the interior of the stand 6 is prevented from being locally overheated.
