Abstract

PURPOSE:To give a soft recovery characteristic by a method wherein a region is provided the fails to let the main current through but stores up carriers from a p-n junction during a period of forward energization. CONSTITUTION:Hihgly doped p type regions 3 are provided separated from each other and, in an area where there is no such a region, an insulating layer 6 is provided to isolate an electrode 5 from the highly doped p type regions 3. This setup enables a region 2 directly under the p type region 3 to work as conventional diode and a regin 2' directly under the insulating layer 6 to work as carrier storage through which the main current fails to flow. That is to say, the carriers stored up during a period of forward energization, by leaving the region 2' by diffusion to flow into the diode region 2, supplies a reverse current as indicated by a gently sloping broken line B. The result is a soft recovery characteristic a denoted by a slid line C.
