Abstract
Un dispositivo transistor que comprende un cuerpo semiconductor al que son aplicados uno junto al otro un electrodo emisor y un electrodo de base en la forma de electrodos de aleación, cuyas zonas asociadas de material semiconductor recristalizado están en contacto con la zona de base, caracterizado por el hecho de que el material recristalizado de al menos uno de estos electrodos ubicado en el lado alejado del otro electrodo, es eliminado al menos en la mitad de la superficie de contacto de la zona de base inicialmente ocupada por la zona recristalizada.
