Abstract

L'INVENTION CONCERNE LES SEMI-CONDUCTEURS. POUR OBTENIR UN POTENTIEL UNIFORME LE LONG DE LA LIGNE D'AMORCAGE 42 D'UN THYRISTOR, ON FORME UNE REGION D'ALIGNEMENT 50 DU MEME TYPE DE CONDUCTIVITE QUE LA ZONE D'EMETTEUR 32. LE BORD INTERIEUR 52 DE LA REGION 50 ET LA LIGNE D'AMORCAGE 42 FORMENT DES CERCLES CONCENTRIQUES. CETTE STRUCTURE PERMET DE COMPENSER UN DEFAUT D'ALIGNEMENT ENTRE LES MASQUES QUE L'ON UTILISE RESPECTIVEMENT POUR FORMER L'EMETTEUR 32 ET LA GACHETTE 62. APPLICATION AUX THYRISTORS.THE INVENTION CONCERNS SEMICONDUCTORS. TO OBTAIN A UNIFORM POTENTIAL ALONG THE FIRING LINE 42 OF A THYRISTOR, AN ALIGNMENT REGION 50 IS FORMED OF THE SAME TYPE OF CONDUCTIVITY AS THE EMITTER ZONE 32. THE INNER EDGE 52 OF THE REGION 50 AND THE PRIMER LINE 42 FORM CONCENTRIC CIRCLES. THIS STRUCTURE ALLOWS TO COMPENSATE FOR AN ALIGNMENT FAULT BETWEEN THE MASKS THAT ARE USED RESPECTIVELY TO TRAIN THE TRANSMITTER 32 AND THE TRIGGER 62. APPLICATION TO THYRISTORS.
