Title: Procede de fabrication d'un dispositif a semi-conducteur programmable sous forme d'antifusible
Inventor: SOLO DE ZALDIVAR JOSE
IPC: H01L27/115
Filed: 1996-03-18
Abstract: L'invention concerne un procédé de fabrication d'un élément à semi-conducteur programmable sous forme d'un dispositif antifusible comprenant une couche mince (3) d'oxyde de silicium entre deux régions constituant des électrodes (4, 5), de manière à créer un couplage entre lesdites régions par claquage électrique dans l'oxyde. D'après l'invention, on effectue d'abord une implantation d'azote au niveau de la zone de l'oxyde à créer, de manière à obtenir une couche mince contenant de l'azote au niveau de la surface, ce qui produit un effet de décélération d'oxydation. On obtient ensuite l'oxyde (3) par oxydation thermique. Grâce à l'effet de décélération de l'oxydation de la couche contenant de l'azote, on peut obtenir une couche d'oxyde extrêmement mince, par exemple de 5mm d'épaisseur, de façon reproductible pendant une durée d'oxydation suffisamment longue. Etant donné l'épaisseur extrêmement réduite de ladite couche d'oxyde, on peut utiliser une tension de programmation inférieure à 10 volts. De plus, l'oxyde obtenu est d'excellente qualité et sensiblement exempt de trous d'aiguille. On peut combiner le dispositif antifusible avec une mémoire EEPROM séparée de la surface par un oxyde tunnel (18) présentant une épaisseur de 10nm, par exemple, et obtenu dans la même étape d'oxydation sur des parties de la surface non dopées à l'azote.
