An ashing treatment is performed on the first photoresist pattern to remove the photoresist layer in the photoresist-partially-retained-region and to thin the photoresist layer in the photoresist-entirely-retained-region, so that a second photoresist pattern is generated. Thereafter, the passivation layer is etched using the second photoresist pattern as a mask to thin the passivation layer in the photoresist-partially-retained-region and to reduce roughness of the rough top surface in the photoresist-partially-retained-region. Therefore, process stability is raised.

  • Patent number: 10411121
    Abstract: The reliability of a semiconductor device is improved. A first insulating film and a protective film are formed on a semiconductor substrate. The first insulating film and the protective film of a first region are selectively removed, and an insulating film is formed on the exposed semiconductor substrate. In a state where the first insulating film in a second region, a third region, and a fourth region is covered with the protective film, the semiconductor substrate is heat-treated in an atmosphere containing nitrogen, thereby introducing nitrogen to the interface between the semiconductor substrate and the second insulating film in the first region. In other words, a nitrogen introduction point is formed on the interface between the semiconductor substrate and the second insulating film. In this configuration, the protective film acts as an anti-nitriding film.
