Semiconductor wafer, semiconductor device and method of manufacturing the same, circuit board, and electronic equipment

摘要

A semiconductor wafer includes a redistribution layer which is electrically connected with a pad which is an end portion of an interconnect, a first resin layer which is formed over the redistribution layer, a second resin layer which is formed over the first resin layer and covers the side surface of the first resin layer, and an external terminal which is formed to be electrically connected with the redistribution layer in a manner to avoid the pad.
