| 摘要 |
The invention relates to a method for mechanically separating a laminar structure (8) from a carrier assembly (1a) comprising or consisting of a first carrier (1), wherein the laminar structure (8) comprises a wafer (7) and optionally a second, stretchable carrier (20), comprising the following steps: a) providing a layer system (1a, 8) comprising the carrier assembly (1a) and the laminar structure (8), b) creating a mechanical stress in the region of the boundary surface between the carrier assembly (1a) and the laminar structure (8), so that the laminar structure (8) is separated from the carrier assembly (1a), by a method comprising i) the steps: i a) providing a separating aid (29), i b) fixing the separating aid (29) on the second carrier (20) such that, during the separating operation, the second carrier (20) remains fixed to the separating aid (29) directly behind a separating front (33) occurring during separation, and i c) mechanically separating the laminar structure (8) from the carrier assembly (1a) by using a separating front (33), and/or ii) the following step: ii) creating a vibration in the layer system (1a, 8), and/or iii) the following step: iii) changing the temperature of the layer system (1a, 8) or parts of the layer system (1a, 8) with the proviso that, if the method does not include the steps i a) - i c), the steps ii) and/or iii) lead to complete separation of the laminar structure from the carrier assembly. |
