Abstract:
A semiconductor device with a large storage capacity per unit area is provided. The semiconductor device includes a first insulator including a first opening, a first conductor that is over the first insulator and includes a second opening, a second insulator that is over the first insulator and includes a third opening, and an oxide penetrating the first opening, the second opening, and the third opening. The oxide includes a first region at least in the first opening, a second region at least in the second opening, and a third region at least in the third opening. The resistances of the first region and the third region are lower than the resistance of the second region.

Claim (Index 12):
A method for manufacturing a semiconductor device, comprising the steps of:\n forming a first insulating film; forming a first conductive film over the first insulating film; forming a second insulating film over the first conductive film; processing the second insulating film, the first conductive film, and the first insulating film to form a first insulator comprising a first opening, a first conductor that is over the first insulator and comprises a second opening, and a second insulator that is over the first conductor and comprises a third opening; processing the first insulator and the second insulator to make a diameter of the first opening and a diameter of the third opening larger than a diameter of the second opening; forming a third insulator to be in contact with the first insulator, the first conductor, and the second insulator in the first opening, the second opening, and the third opening; forming a first nitride comprising at least one of silicon and a metal element to be in contact with the third insulator; processing the first nitride to form a second nitride having a sidewall surface substantially aligned with a sidewall surface of an inner wall of the third insulator in the first opening and the third opening; and forming an oxide to be in contact with the third insulator and the second nitride in the first opening, the second opening, and the third opening.
