Claim:
1. A semiconductor device comprising: a first conductor and a second conductor; a first insulator in contact with a top surface of the first conductor and a top surface of the second conductor; a second insulator over the first insulator; an oxide semiconductor overlapping with the first conductor with the first insulator and the second insulator interposed therebetween; a third insulator over the oxide semiconductor; a third conductor overlapping with the oxide semiconductor with the third insulator interposed therebetween; a fourth insulator over and in direct contact with the third conductor, a side surface of the third insulator, the oxide semiconductor, and the first insulator; a fifth insulator over the fourth insulator; a fourth conductor in contact with the oxide semiconductor; a fifth conductor in contact with the oxide semiconductor; and a sixth conductor overlapping with the second conductor with the first insulator and the fourth insulator interposed therebetween, wherein the second insulator includes an opening overlapping with the second conductor, and wherein the fourth insulator is in direct contact with the first insulator through the opening of the second insulator.
