IPC: H01L29/861
Filed: 1978-08-09
Abstract: PURPOSE: To minimize a dispersion of punch-through voltage due to the thickness of P epitaxial layer by suppressing a growth of depletion layer with P +  layer provided uniformly in the thickness direction of P type Si epitaxial layer.  
     CONSTITUTION: P +  ion-impregnated layer 9 and P -  epitaxial layer 2 are laminated on N type Si substrate 1. The layer 2 is isolated with N type layer 4 provided by SiO 2  mask 3. An opening is then arranged in SiO 2  on the layer 2 and P +  layer 10 is formed to reach P +  layer 9. Next, SiO 2  is again subjected to a selective opening to form N type emitter layer 5, covered with a protective film 6 and then subjected to a selective opening to attach an electrode 7. According to this constitution, P +  layer 9 suppresses the growth of a depletion layer almost all against voltage applied, and a dispersion in punch-through voltage of constant-voltage diode is minimized accordingly. Further P +  layer 10 is effective enough to minimize the growth of depletion layer on the emitter N layer 5 at its end and develop it at the center to punch-through, thus decreasing dispersion under suppressing abnormal punch- through.
