Abstract

There may be presented a method of manufacturing a semiconductor chip. A first layer stack in which first material layers and second material layers are alternately stacked is formed over a semiconductor substrate including a chip region and a scribe lane region, and first crack propagation guides are formed on the first layer stack. A second layer stack is formed on the first layer stack and the first crack propagation guides, and second crack propagation guides are formed. A semiconductor chip is separated from the semiconductor substrate.
