Abstract
A thin film is transferred from an initial substrate onto a final substrate. The process includes the following successive stages: joining of the thin film (112) onto a handle substrate (120) comprising a cleavage zone, elimination of the initial substrate, joining of the thin film (112) with a final substrate (132), and cleavage of the handle substrate (120) following the cleavage zone. The cleavage zone includes a film of micro-bubbles formed by ion implantation. The invention has, in particular, applications in the fabrication of three-dimensional structures of integrated circuits.
