In a method for fabricating a semiconductor device according to the present invention, a groove is formed in a second interlayer insulating film, and then a storage electrode is formed which covers bottom and side surfaces of the groove. A capacitor insulating film is formed on the storage electrode, and a CVD method at a low temperature of 400° C. or lower and annealing with ammonia are repeated to form a TiOxNy film on the capacitor insulating film. A TiN film is formed on the TiOxNy film, and the TiN film is etched using the TiOxNy film as a stopper. The exposed TiOxNy film is then removed to form a plate electrode made of the TiOxNy film and the TiN film.

摘要:
Transmitting portions of a phase-shifting mask include plural first transmitting areas periodically arranged along a first direction and a second direction and a second transmitting area provided in an area surrounded with adjacent four first transmitting areas among the plural first transmitting areas. The first transmitting areas are formed by recessing a board so that a phase difference of substantially 180 degrees in exposure light can be caused between adjacent first transmitting areas. A phase difference of substantially 90 degrees in the exposure light is caused between the second transmitting area and the surrounding first transmitting areas. Thus, isolated patterns arranged at high density can be formed correspondingly to the first transmitting areas and the second transmitting area.

It is an objective of the present invention to provide a lithium-ion rechargeable battery anode which can control the volume change of a primary particle of a negative-electrode active material other than a carbon-based material and that can prevent cracks due to stress caused by the volume change from occurring and extending. There is provided an anode for a lithium-ion rechargeable battery including a primary particle of a negative-electrode active material, a conductive material, and a binder, the negative-electrode active material including at least one of silicon and tin, and at least one element selected from elements that do not chemically react with lithium, in which holes are present both in an inner core region in the central region of the primary particle of the negative-electrode active material and in a periphery region that covers the inner core region.

After protective insulating films are formed on first to third active regions, the protective insulating films formed on the first and third active regions are removed. Subsequently, an insulating film to be a first gate insulating film is formed on each of the first and third active regions, and then, the protective insulating film formed on the second active region is removed. Next, an insulating film to be a second gate insulating film is formed on the second active region, and then, the insulating film to be the first gate insulating film formed on the third active region is removed. Finally, an insulating film to be a third gate insulating film is formed on the third active region.
