There are provided methods of fabricating a metal-insulator-metal (MIM) capacitor employing a metal nitride layer as a lower electrode. The method includes forming an insulating layer on a semiconductor substrate. A metal source gas and a nitride gas are supplied to the insulating layer, thereby depositing a metal nitride. A flushing gas including nitrogen is supplied to the metal nitride to enhance nitridation reaction. Along with the supply of a metal source gas and a nitride gas, the operation of supplying a flushing gas is performed at least one time alternately and repeatedly, thereby forming a metal nitride layer. |
