Abstract
This process comprises steps of: a) providing a first substrate comprising the active layer made of a first material of Young's modulus Eand of thickness h; b) providing a second substrate made of a second material of Young's modulus Eand of thickness h; c) bending the first substrate and the second substrate such that they each have a curved shape of a radius of curvature R; d) joining the second substrate to the active layer such that the second substrate closely follows the shape of the first substrate; and e) re-establishing the initial at-rest shape of the second substrate, the process being noteworthy in that the second material of the second substrate is a flexible material respecting the relationship E/E<10, in that the thickness of the second substrate respects the relationship h/h≧10, and in that the radius of curvature respects the relationship
