Abstract
Temporary substrates may include a bonding surface prepared for receiving an additional substrate that will transfer a thin layer. Such substrates may include a principal part or support and a surface layer thereon with the surface layer having a plurality of inserts therein. The inserts are made of a material having a coefficient of thermal expansion that is significantly different from that of the material constituting the surface layer. Processing methods for transferring a selected portion of an original substrate may involve such temporary substrates and productions methods may produce such temporary substrates.
