Methods of fabricating MIM capacitors are provided. One example method includes forming an insulating layer including a void on a semiconductor substrate, forming a first hole connected to the void by patterning the insulating layer, forming a lower electrode by forming a tungsten layer filling in the first hole such that the tungsten flows into the void, forming a dielectric layer, forming a second hole penetrating the dielectric layer and protruding toward the insulating layer, forming a connecting contact connected to the lower electrode by filling in the second hole, and forming an upper electrode on the dielectric layer.
