Original Abstract Submitted
A semiconductor device that can be miniaturized or highly integrated is provided. The semiconductor device includes a first insulator, a second insulator over the first insulator, and a memory cell including a transistor and a capacitor. The transistor includes an oxide over the first insulator, a first conductor and a second conductor over the oxide, a third insulator over the oxide, and a third conductor over the third insulator. The third insulator and the third conductor are located in a first opening of the second insulator. The capacitor includes a fourth conductor in contact with a top surface of the second conductor, a fourth insulator over the fourth conductor, and a fifth conductor over the fourth insulator. The fourth conductor, the fourth insulator, and the fifth conductor are located in a second opening of the second insulator. A third opening is formed in the first insulator, the second insulator, and the first conductor. A sixth conductor is located in the third opening. The sixth conductor includes a region in contact with part of a top surface of the first conductor and part of a side surface of the first conductor in each of a plurality of layers.
