Method for manufacturing a structure comprising a thin layer transferred onto a support provided with a charge trapping layer

Abstract

A method for manufacturing a structure comprising a thin layer transferred onto a support provided with a charge trapping layer, the method comprising the following steps: —preparing the support comprising forming the trapping layer on a base substrate, the trapping layer having a hydrogen concentration of less than 10{circumflex over ( )}18 at/cm{circumflex over ( )}; —joining the support to a donor substrate by way of a dielectric layer having a hydrogen concentration of less than 10{circumflex over ( )}20 at/cm{circumflex over ( )}3 or comprising a barrier preventing the diffusion of hydrogen toward the trapping layer or having low hydrogen diffusivity; —removing part of the donor substrate to form the thin layer; the manufacturing method exposing the structure to a temperature below a maximum temperature of 1000° C. The present disclosure also relates to a structure obtained at the end of this method.
