Brief description of at least one pair of structures comprising at least one layer useful postponed on a substrate

摘要

The invention relates to a process for the production of at least one pair of structures (51,52) each comprising a layer of the useful (110,120) mounted on a substrate (71,2). this method is remarkable in that it comprises the steps consisting in: a) preparing a structure of rank 1 comprising a layer of the useful mounted on a substrate support (2), b) form an embrittlement zone to the inside of said layer, so as to define a useful (110) and a layer which is useful to the rear (120), c) to adhere a stiffener (71) on the said layer useful (110), d) to be detached from the stack of layers along the zone of weakness, in order to obtain two structures of rank 2, the first (51) comprising the said substrate (2) and the said layer useful rear (120) and the second (52) comprising the said substrate stiffener (71) and the said layer useful (110) .applications in the fields of electronics, the optoelectronic or optical.
