Abstract

A semiconductor device includes a conductive line that extends in a first direction on a substrate, a first oxide semiconductor layer, including a first crystalline oxide semiconductor material containing a first metal element, on the conductive line, a second oxide semiconductor layer, which is in physical contact with the first oxide semiconductor layer and is connected to the conductive line, on the conductive line, a gate electrode that extends in a second direction, which crosses the first direction, on a side of the second oxide semiconductor layer, and a capacitor structure connected to the second oxide semiconductor layer on the second oxide semiconductor layer and the gate electrode, wherein the second oxide semiconductor layer includes a second crystalline oxide semiconductor material containing the first metal element and second and third metal elements, which are different from the first metal element.
