Abstract
PURPOSE:To improve the current amplification factor of the semiconductor device by forming an N type layer on a part of a P type layer and forming a P type layer on a part thereof, thereby reducing a resistance between the emitter and the base of a transistor where a reverse conducting diode is built-in. CONSTITUTION:A transistor is formed on an N type collector layer 2, a P type base layer 3 and an N type emitter layer 4. An N type base layer 5 having slightly higher density than the layer 3 is formed on a part of the layer 3, and a P type emitter layer 6 having higher density than the layer 5 is formed on the layer 5. Electrodes 8 and 10 are connected by an external lead wire 12, the layers 3 and 5 are shorted by electrodes 9, 14, and the electrode 9 is connected to the base electrode 7. Further, the junction J3 between the layers 6 and 5 is connected as a reverse diode between the base and the emitter so that, when the base is biased forwardly, the diode may not be reversely biased to eliminate a reactive current flow.
