Abstract
A manufacturing method of a semiconductor device includes: forming a mark on a surface of a semiconductor wafer, at least a part of the mark being disposed in a planned-peripheral region, the planned-peripheral region being located around a respective planned-element region where a semiconductor element is to be formed; forming the semiconductor element in the planned-element region using the mark; forming a film that extends across a range including the planned-element region or the planned-peripheral region in the surface so as to cover at least a part of the mark with the film, after forming the semiconductor element; and after forming the film, cutting the semiconductor wafer along a dicing region, the dicing region located around the planned-peripheral region.
