Abstract: A semiconductor wafer forms on a mold containing a dopant. The dopant dopes a melt region adjacent the mold. There, dopant concentration is higher than in the melt bulk. A wafer starts solidifying. Dopant diffuses poorly in solid semiconductor. After a wafer starts solidifying, dopant cannot enter the melt. Afterwards, the concentration of dopant in the melt adjacent the wafer surface is less than what was present where the wafer began to form. New wafer regions grow from a melt region whose dopant concentration lessens over time. This establishes a dopant gradient in the wafer, with higher concentration adjacent the mold. The gradient can be tailored. A gradient gives rise to a field that can function as a drift or back surface field. Solar collectors can have open grid conductors and better optical reflectors on the back surface, made possible by the intrinsic back surface field.

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.

Abstract: Roughness is eliminated and planarization is achieved by a metal oxide film on a surface of a lower electrode. Consequently, damage on a capacitive film caused by the roughness of the lower electrode is reduced. Furthermore, physical damage on the capacitive film is reduced by forming a first layer of an upper electrode by, for example, CVD. Consequently, the damage on the capacitive film is suppressed, and the reliability of the capacitive film is improved. Furthermore, not by forming the whole upper electrode by the CVD or the like, but by forming a second layer by PCD or the like on the first layer, an increase in resistance of the upper electrode is suppressed as well.
