Abstract
A semiconductor device with improved reliability is provided. The semiconductor device includes a first oxide, a second oxide over the first oxide, a third oxide over the second oxide, and an insulator over the third oxide. The second oxide contains In, an element M (M is Al, Ga, Y, or Sn), and Zn. The first oxide and the third oxide each include a region whose In concentration is lower than that in the second oxide.
