Abstract
A highly reliable semiconductor device is provided. The semiconductor device includes a first oxide; a second oxide, a first layer, and a second layer over the first oxide; an insulator over the second oxide; a first conductor over the insulator; a second conductor over the first layer; and a third conductor over the second layer. Each of the first and second layers includes a region with a thickness ranging from 0.5 nm to 3 nm. Each of the second and third conductors contains a conductive material having the physical property of extracting hydrogen.
