Title: Three terminal control commutation element and its producing method
Inventor: YAMAGAMI KOUZOU
IPC: H01L29/74
Filed: 1978-07-27
Abstract: PURPOSE:To improve dV/dt resist amount by varying the impurity density of P type base area near the junction with N base area and by stabilizing it at other areas. CONSTITUTION:P type emitter area 2 is formed on one side of N type Si unicrystalline base plate 1. Next, P type impurity is shallowly diffused to have a surface of relatively lower density than the other side of the base plate 1, forming a part 3 of P type base area 3. Next, the remaining area 3b is formed to be in a fixed stable density of impurities. Thus, on one side of the base plate 1 is formed P type base area 3. Next, N type emitter area 4 is formed on a part of area 3 surface layer, then formed are an anode electrode 6, a cathode electrode 5, a gate area 7. Under this structure, a traverse resistance of the area 3 becomes lower so that the impression between electrodes 5, 6 to make the electrode 5 in positive electric potential increases the traverse current in area 3 and decreases the current flowing into area 4 among the current flowing in the junction between areas 1 and 3. Thus, dV/dt resist amount becomes greater.

Both the amplifier 53 and a head changeover switch 56 are kept turned on while the signal received from a CH1 head control signal generating circuit 60a is kept at H. Thus a recording current flows to a CH1 head 14. While a head changeover switch 55 and a reproducing preamplifier 61 are kept turned on while said signal received from the circuit 60a is kept at L. Thus the reproduced signal produced from a preceding track is obtained from the head 14.
