Abstract:
A MIM capacitor includes a lower electrode disposed on a semiconductor substrate. A dielectric layer is disposed on the lower electrode to completely cover an exposed surface of the lower electrode. An upper electrode is disposed on the dielectric layer. A method for forming a MIM capacitor includes forming a lower electrode on a semiconductor substrate. A dielectric layer and an upper metal layer are formed on an entire surface of the substrate to cover the lower electrode. The dielectric and upper metal layers are patterned on the lower electrode.
