Abstract
A semiconductor device includes a capacitor including a lower electrode an upper electrode, and a dielectric layer between the lower electrode and the upper electrode. The lower electrode includes ABOwhere 'A' is a first metal element and 'B' is a second metal element having a work function greater than that of the first metal element. The dielectric layer includes CDOwhere ‘C’ is a third metal element and ‘D’ is a fourth metal element. The lower electrode includes a first layer and a second layer which are alternately and repeatedly stacked. The first layer includes the first metal element and oxygen. The second layer includes the second metal element and oxygen. The dielectric layer is in contact with the lower electrode at a first contact surface the first contact surface corresponding to the second layer.
