Abstract

Un dispositif à semi-conducteurs comprend une couche en InGaAs de type n**+ à concentration élevée 26 qui est formée sur la surface du dispositif; une électrode d'émetteur 27 consistant en un métal réfractaire capable de former un contact ohmique sans alliage, qui est formée sur la couche en InGaAs de type n**+ à concentration élevée, et une région de base externe 30 qui est formée au voisinage de l'électrode d'émetteur, par une opération de diffusion utilisant à titre de masque l'électrode d'émetteur et sa paroi latérale.
