Abstract
A metal-insulator-metal (MIM) capacitor includes a bottom electrode cup, an insulator cup, and a top electrode. The bottom electrode cup includes a laterally-extending bottom electrode cup base, and a bottom electrode cup sidewall extending upwardly from the laterally-extending bottom electrode cup base. The insulator cup is formed in an opening defined by the bottom electrode cup, and includes a laterally-extending insulator cup base formed over the laterally-extending bottom electrode cup base, and an insulator cup sidewall extending upwardly from the laterally-extending insulator cup base. A dielectric sidewall spacer is located between the insulator cup sidewall and the bottom electrode cup sidewall. The top electrode is formed in an opening defined by the insulator cup.
