METHOD OF MANUFACTURING SEMICONDUCTOR PACKAGE USING ALIGNMENT MARK ON WAFER
A method of manufacturing a semiconductor package and a semiconductor package in which positional alignment between a wafer and a substrate until the wafer is mounted and packaged on the substrate is achieved accurately. A wafer is mounted on a package substrate by using first alignment marks and D-cuts as benchmarks, and then a mold resin layer is formed on the wafer in a state in which the first alignment mark is exposed. A part of the mold resin layer is removed by using the D-cuts exposed from the mold resin layer as benchmarks, so that the first alignment marks can be visually recognized. A second alignment marks are formed on the mold resin layer by using the first alignment marks as benchmarks. A Cu redistribution layer to be conducted to a pad portion is formed on a mold resin layer by using the second alignment marks as benchmarks.
