Fish & Richardson P.C.
Transistor, semiconductor device, and electronic device
A highly reliable semiconductor device capable of retaining data for a long period is provided. The transistor includes a first gate electrode, a first gate insulator over the first gate electrode, a first oxide and a second oxide over the first gate insulator, a first conductor over the first oxide, a second conductor over the second oxide, a third oxide covering the first gate insulator, the first oxide, the first conductor, the second oxide, and the second conductor, a second gate insulator over the third oxide, and a second gate electrode over the second gate insulator. An end portion of the second gate electrode is positioned between an end portion of the first conductor and an end portion of the second conductor in a channel length direction.
