    Abstract: A method of processing a substrate is provided. The method includes mounting a substrate on a concave mounting surface of a mounting table and deforming a surface of the substrate into a concave shape; detecting, by a height sensor, a height of the surface of the substrate in a vertical direction; determining positions of a plurality of first focus points based on height data of the surface of the substrate, detected by the height sensor; and forming a first modification layer in the substrate by irradiating the plurality of first focus points with a laser beam.

    Abstract: A method of manufacturing a semiconductor chip includes preparing a semiconductor substrate having an active surface on which a device layer is provided and an inactive surface opposite to the active surface, the device layer having a integrated circuit (IC) areas and a cut area provided between adjacent IC areas; forming anti-collision recesses in regions of the cut area that are adjacent to corners of the IC areas, each of the anti-collision recesses having rounded internal sidewalls, each of the rounded internal sidewalls corresponding to a respective corner of the adjacent corners; forming a modified portion in the semiconductor substrate by irradiating a cut line of the cut area with a laser; polishing the inactive surface of the semiconductor substrate, wherein cracks propagate from the modified portion in a vertical direction of the semiconductor substrate; and separating the IC areas from each other along the cracks to form semiconductor chips.
