In a manufacturing method of a semiconductor device, a semiconductor substrate having a plurality of semiconductor chips formed on one of principal surfaces of the substrate is cut into the plurality of semiconductor chips through dicing. A first cutting process is formed on one of the principal surfaces of the substrate to produce two cutting grooves between two neighboring ones of the plurality of semiconductor chips, each cutting groove being adjacent to one of the neighboring ones of the plurality of semiconductor chips. A second cutting process is performed on the other of the principal surfaces of the substrate to produce a cutting groove overlapping the two cutting grooves produced by the first cutting process.

A semiconductor device has an alignment mark which can be recognized by a conventional wafer prober. A redistribution layer connects electrodes of the semiconductor device to electrode pads located in predetermined positions of the redistribution layer. Metal posts configured to be provided with external connection electrodes are formed on the electrode pads of the redistribution layer. A mark member made of the same material as the metal posts is formed on the redistribution layer. The mark member serves as an alignment mark located in a predetermined positional relationship with the metal posts.
