Summary: | The invention relates to a method of producing a substrate (16) with a functional layer (12). The method comprises providing a workpiece (2) having a first surface (4) and a second surface (6) opposite the first surface (4), and forming a modified layer (8) inside the workpiece (2), the modified layer (8) comprising a plurality of modified regions. Further, the method comprises, after forming the modified layer (8) inside the workpiece (2), forming the functional layer (12) on the first surface (4) of the workpiece (2) and, after forming the functional layer (12) on the first surface (4) of the workpiece (2), dividing the workpiece (2) along the modified layer (8), thereby obtaining the substrate (16) with the functional layer (12). Dividing the workpiece (2) along the modified layer (8) comprises applying an external stimulus to the workpiece (2). Moreover, the invention relates to a substrate producing system for performing this method. |
