Abstract
A semiconductor device having favorable electrical characteristics is provided. A highly reliable semiconductor device is provided. The semiconductor device includes a metal oxide. The semiconductor device includes a gate electrode, a first insulating film over the gate electrode, the metal oxide over the first insulating film, a pair of electrodes over the metal oxide, and a second insulating film in contact with the metal oxide. The metal oxide includes a first metal oxide and a second metal oxide in contact with a top surface of the first metal oxide. The first metal oxide and the second metal oxide each contain In, an element M (M is gallium, aluminum, silicon, or the like), and Zn. The first metal oxide includes a region having lower crystallinity than the second metal oxide. The second insulating film includes a region whose thickness is smaller than that of the second metal oxide.
