    Abstract: A technique for forming a film of material (12) from a donor substrate (10). The technique has a step of forming a stressed region in a selected manner at a selected depth (20) underneath the surface. An energy source such as pressurized fluid is directed to a selected region of the donor substrate to initiate a controlled cleaving action of the substrate (10) at the selected depth (20), whereupon the cleaving action provides an expanding cleave front to free the donor material from a remaining portion of the donor substrate.

    Abstract translation: 一种用于从供体衬底(10)形成材料(12)的膜的技术。 该技术具有以选定的方式在表面下方的选定深度(20)处形成应力区域的步骤。 诸如加压流体的能量源被引导到供体基底的选定区域,以在所选择的深度(20)处引发基底(10)的受控切割作用,因此所述切割动作提供扩张切割前缘以释放供体 来自供体衬底的剩余部分的材料。

    Abstract: The invention relates to a method for producing a multi-layer assembly. The method according to the invention comprises at least the following steps: providing a donor substrate (2) for removing a solid layer (4), in particular a wafer; producing modifications (12), in particular by means of laser beams (10), in the donor substrate (2) in order to specify a crack course; providing a carrier substrate (6) for holding the solid layer (4); bonding the carrier substrate (6) to the donor substrate (2) by means of a bonding layer (8), wherein the carrier substrate (6) is provided for increasing the mechanical strength of the solid layer (4) for the further processing, which solid layer is to be removed; arranging or producing a stress-producing layer (16) on the carrier substrate (6); thermally loading the stress-producing layer (16) in order to produce stresses in the donor substrate (2), wherein a crack is triggered by the stress production, which crack propagates along the specified crack course in order to remove the solid layer (4) from the donor substrate (2) such that the solid layer (4) is removed together with the bonded carrier substrate (6).
