摘要:
The invention relates to a method of producing a substrate. The method comprises providing a workpiece having a first surface and a second surface opposite the first surface, and providing a carrier having a first surface and a second surface opposite the first surface. The method further comprises attaching the carrier to the workpiece, wherein at least a peripheral portion of the first surface of the carrier is attached to the first surface of the workpiece, and forming a modified layer inside the workpiece. Moreover, the method comprises dividing the workpiece along the modified layer, thereby obtaining the substrate, wherein the substrate has the carrier attached thereto, and removing carrier material from the side of the second surface of the carrier in a central portion of the carrier so as to form a recess in the carrier. The invention further relates to a substrate producing system for performing this method.
