    摘要: Methods and apparatus are disclosed for manufacturing metal-insulator-metal (MIM) capacitors. The MIM capacitors may comprise an electrode, which may be a top or bottom electrode, which has a bottle neck. The MIM capacitors may comprise an electrode, which may be a top or bottom electrode, in contact with a sidewall of a via. The sidewall contact or the bottle neck of the electrode may burn out to form a high impedance path when the leakage current exceeds a specification, while the sidewall contact or the bottle neck of the electrode has no impact for normal MIM operations. The MIM capacitors may be used as decoupling capacitors.
