Abstract
Transistor épitaxial multicouche dont l'émetteur est formé d'une portion de couche faiblement dopée et d'une région superficielle fortement dopée. La région superficielle d'émetteur est en forme de bande, à distance de la zone de contact de base et de l'axe de la portion de couche faiblement dopée. Protection de transistors de commutation vis-à-vis du second claquage.
