Abstract

L'invention a pour objet un dispositif de prise de contact sur un élément semiconducteur. La face supérieure de l'élément en arséniure de gallium est recouverte en partie de titane formant avec l'arséniure de gallium un contact ohmique de faible résistivité. L'ensemble est recouvert d'or formant avec l'As Ga un contact ohmique de résistivité beaucoup plus élevée. Les lignes de courant sont ainsi localisées sous le titane. L'invention s'applique tout particulièrement aux diodes << laser >>.
