Methods of manufacturing a semiconductor chip are provided. The methods may include providing a semiconductor substrate including integrated circuit regions and a cut region. The cut region may be between the integrated circuit regions. The methods may also include forming a modified layer by emitting a laser beam into the semiconductor substrate along the cut region, polishing an inactive surface of the semiconductor substrate to propagate a crack from the modified layer, and separating the integrated circuit regions along the crack. The cut region may include a plurality of multilayer metal patterns on an active surface of the semiconductor substrate, which is opposite to the inactive surface of the semiconductor substrate. The plurality of multilayer metal patterns may form a pyramid structure when viewed in cross section.

Methods of manufacturing semiconductor chip

A semiconductor device includes a semiconductor substrate having a scribe lane defined therein. A plurality of semiconductor chips is formed on an upper surface of the semiconductor substrate. At least one conductive structure is arranged on an upper surface of the semiconductor substrate, within the scribe lane thereof. A fillet is arranged on at least one side surface of the conductive structure. The fillet is configured to induce a cut line which spreads along the scribe lane, through a central portion of the conductive structure.
