Abstract

Contact pour composant électronique La présente description concerne un procédé de fabrication d’un contact (250) sur une région semiconductrice (124, 126) d’un composant électronique (200), ledit procédé comprenant :- une étape de formation d’un empilement de couches adaptées à être électriquement conductrices sur les parois latérales et au fond d’un orifice (251) traversant une région diélectrique (142) du composant électronique, à partir d’une première surface (142A) de ladite région diélectrique, le fond de l’orifice débouchant au droit de la région semiconductrice, ladite étape de formation comprenant la formation d’une couche (253) de polysilicium et d’une couche d’un premier métal en contact avec la couche de polysilicium, ledit premier métal étant choisi dans le groupe des terres rares, et étant adapté à former avec le polysilicium un siliciure de métal ; puis- une étape de recuit thermique adaptée à faire réagir le premier métal et le polysilicium, conduisant à la formation d’une couche (256) de siliciure de métal comprenant au moins une portion s’étendant dans la direction longitudinale de l’orifice.
