摘要： The invention relates to a method of removing a peripheral zone (62) of adhesive while using a layer of adhesive (6) in the process of assembling and transferring a layer (41) of material coming from a source substrate (4) and placed on a support substrate (5). The method is remarkable in that it consists in bonding the two substrates (4 and 5) together by means of an intermediate layer of curable adhesive (6), in curing only that zone (61) of the layer of adhesive (6) which extends facing the front face (43) of said layer (41) of material to be transferred, in removing the zone (62) of non-cured adhesive, and in detaching said layer (41) to be transferred from the remainder (42) of the source substrate. The invention is applicable to fabricating a composite substrate in the fields of electronics, optoelectronics, or optics.

摘要： The invention concerns a method for transferring a layer of material (41) deriving from a source substrate (4) onto a support substrate (5), comprising at least the steps consisting in : depositing additional material (6) on at least one of the front faces of the source substrate (4) and the support substrate (5) and applying said two substrates (4, 5) against each other; then detaching said layer to be transferred (41) from the source substrate (4) along a zone of weakness (43) by applying a stress of mechanical origin. This method is remarkable in that prior to the step of depositing the material (6), at least one recess (56) for receiving excess additional material (6) is formed in at least one of the two substrates (4, 5), said recess opening onto the front face of said substrate. Application to the fabrication of a composite substrate in the fields of electronics, optoelectronics and optics.
