A pillar bump structure, and a method for forming the same includes forming, on a semiconductor substrate, a blanket liner followed by a seed layer including a noble metal. A first photoresist layer is formed directly above the seed layer followed by the formation of a first plurality of openings within the photoresist layer. A first conductive material is deposited within each of the first plurality of openings to form first pillar bumps. The first photoresist layer is removed from the semiconductor structure followed by removal of portions of the seed layer extending outward from the first pillar bumps, a portion of the seed layer remains underneath the first pillar bumps.

In a method of manufacturing a semiconductor device according to one embodiment, after a semiconductor wafer including a non-volatile memory, a bonding pad and an insulating film comprised of an organic material is provided, a probe needle is contacted to a surface of the bonding pad located in a second region, and a data is written to the non-volatile memory. Here, the insulating film is formed by performing a first heat treatment to the organic material. Also, after a second heat treatment is performed to the semiconductor wafer, and the non-volatile memory to which the data is written is checked, a barrier layer and a first solder material are formed on the surface of the bonding pad located in a first region by using an electroplating method. Further, a bump electrode is formed in the first region by performing a third heat treatment to the first solder material.
