Patent ID: 8501588

Claim:
A method for making a semiconductor on insulator structure, comprising: a) forming, on a surface of a semiconductor substrate, as a final substrate, a semiconducting layer, doped with elements from columns III and V of the Periodic Table so as to form a ground plane; b) forming a dielectric layer either on a surface made from a semiconducting material of a second substrate, as a source substrate, which is made from a semiconducting material or includes a superficial layer made from a semiconducting material; or on the final substrate and in contact with the ground plane; c) then assembling, by direct adhesion of the source substrate, on the final substrate, the layer forming a ground plane between the final substrate and the source substrate, the dielectric layer being between the source substrate and the ground plane; and d) then thinning the source substrate, leaving, on the surface of the semiconductor structure, a film made from a semiconducting material.
