PROCESS FOR JOINING AND SEPARATING SUBSTRATES

摘要

The invention relates to a process for modifying a substrate (10) comprising: (a) providing an initial substrate (10) having a face (10b) for bonding and an opposing face (10r); (b) providing a support substrate (25); wherein either the bonding face (10b) of the initial substrate (10), and/or a face of the support substrate (25), is provided with an electromagnetic radiation absorbing layer (24), wherein the support substrate (25) is substantially transparent to a wavelength of electromagnetic radiation (c) performing bonding to join the bonding face (10b) of the initial substrate (10) to the support substrate (25) via the electromagnetic radiation absorbing layer (24); (e) carrying out irradiation of the electromagnetic radiation absorbing layer (24) through the substantially transparent support substrate (25) to induce separation of the support substrate (25).
