Abstract: A method of manufacturing a semiconductor device includes following steps. The substrate has a dummy region and a memory cell region. A plurality of first stack structures are formed over the substrate in the memory cell region. At least one second stack structure is formed over the substrate in the dummy region. A conductive layer is formed over the substrate to cover the first stack structures and the at least one second stack structure. A planarization process is performed on the conductive layer to expose top surfaces of the first stack structures and the at least one second stack structure. The conductive layer is patterned to form an erase gate between adjacent two first stack structures, and to form first and second select gates outside the adjacent two first stack structures.

Abstract: In a method for manufacturing a semiconductor device, a semiconductor substrate having a top surface is provided. A top metal layer is formed in the top surface. A first passivation layer is formed to cover the top metal layer and the top surface. The first passivation layer has a via hole exposing a portion of the top metal layer. A redistribution layer is formed to cover the first passivation layer, the portion of the top metal layer, and a side surface of the via hole. The redistribution layer includes an overhang structure over the via hole. An etching process is performed on the redistribution layer to remove the overhang structure and a portion of the redistribution layer to expose a portion of the first passivation layer. A second passivation layer is formed to cover the redistribution layer and the portion of the first passivation layer.
