Abstract

L’invention porte sur un procédé de fabrication d’une structure composite comprenant une couche mince de carbure de silicium, SiC, monocristallin (12) disposée un substrat support de SiC polycristallin (20). Ce procédé comprend les étapes suivantes : - formation d’une couche de SiC polycristallin (11) sur un substrat donneur dont au moins une portion superficielle est en SiC monocristallin, - avant ou après ladite formation, implantation d’espèces ioniques dans ladite portion superficielle du substrat donneur de sorte à former un plan de fragilisation délimitant une couche mince de SiC monocristallin (12) à transférer, - après ladite implantation et ladite formation, collage du substrat donneur et du substrat support de SiC polycristallin (20), la couche de SiC polycristallin (11) étant à l’interface de collage, et détachement du substrat donneur le long du plan de fragilisation de sorte à transférer la couche de SiC polycristallin (11) et la couche mince de SiC monocristallin (12) sur le substrat support de SiC polycristallin (20).
