Abstract:
A method for producing a semiconductor device includes dicing, at a scribe area of a semiconductor wafer, the semiconductor wafer into semiconductor chips including respective circuit areas formed on the semiconductor wafer, the scribe area being provided between the circuit areas and extending in a first direction in a plan view, wherein the scribe area includes a first area extending in the first direction and second areas including monitor pads and extending in the first direction and located on both sides of the first area, wherein the method includes removing at least portions of the monitor pads by emitting laser beam to the second areas before the dicing, and wherein, in the dicing, the semiconductor wafer is diced at the first area.
