PROCESS FOR MANUFACTURING A COMPOSITE STRUCTURE

摘要

The disclosure relates to a process for manufacturing a composite structure, the process comprising the following steps: a) providing a donor substrate and a carrier substrate; b) forming a dielectric layer; c) forming a covering layer; d) forming a weakened zone in the donor substrate; e) joining the carrier substrate and the donor substrate via a contact surface having an outline; f) fracturing the donor substrate via the weakened zone, steps b) and e) being executed so that the outline is inscribed in the outline, and step c) being executed so that the covering layer covers the peripheral surface of the dielectric layer.
