Abstract

Cette invention concerne une structure de vanne de Spin à magnéto-résistance géante comportant des couches multiples de matériau ferromagnétique (26,30) et un matériau conducteur non magnétique (28) que l'on peut intégrer d'un bloc dans des circuits de silicium (50) en faisant dans un premier temps croître une couche tampon réceptrice (24) sur une tranche de silicium (22). La couche tampon réceptrice est constituée par une couche d'oxyde monocristallin qui est séparée de la tranche de silicium par une couche d'oxyde amorphe (32) de silice. La couche oxyde amorphe dissipe les contrainte et autorise la croissance d'une couche tampon réceptrice d'oxyde monocristallin de haute qualité. Cette couche tampon réceptrice est appariée au niveau de la grille tant avec la tranche de silicium sous-jacente qu'avec la couche ferromagnétique qui la recouvre. Toute inadéquation de grille entre la couche tampon réceptrice et le substrat de silicium sous-jacent es absorbée par la couche oxyde amorphe.
