Abstract

A semiconductor device includes a first electrode, an oxide semiconductor layer electrically connected to the first electrode and disposed above the first electrode, a gate electrode facing the oxide semiconductor layer with an insulating film interposed therebetween, and a second electrode including a first conductive layer electrically connected to the oxide semiconductor layer and disposed above the oxide semiconductor layer, the first conductive layer containing oxygen, indium, and tin. The second electrode further includes a second conductive layer in contact with the first conductive layer and containing oxygen and a first metal and a third conductive layer in contact with the second conductive layer and containing the first metal.
