A capacitor structure formed on an insulation layer includes a lower electrode formed on a surface of the insulation layer, a dielectric layer formed on a surface of the lower electrode, an upper electrode formed on a surface of the dielectric layer, a first spacer formed on a side portion of the upper electrode, and a second spacer formed on a side portion of the first spacer and a side portion of the lower electrode. This capacitor structure is formed by depositing a metal-insulator-metal capacitor stack on top of a via, masking and etching an upper electrode of the metal-insulator-metal capacitor stack, depositing and etching a first spacer on an edge surface of the upper electrode, defining a lower electrode of the metal-insulator-metal capacitor based on the first spacer, depositing and etching a second spacer on a surface of the first spacer and an edge of the lower electrode, and forming a wiring layer on a surface of the upper electrode and a surface of the second spacer. This capacitor structure provides a capacitor that is not prone to leakage down the capacitor sidewall and the corresponding method of manufacture provides a capacitor that is fabricated with increased efficiency (e.g., fewer mask steps).
