摘要:
A metal-insulator-metal (MIM) capacitor includes a lower electrode, a dielectric layer, and an upper electrode. The lower electrode includes a first conductive layer, a chemical barrier layer on the first conductive layer, and a second conductive layer on the chemical barrier layer. The chemical barrier layer is between the first and second conductive layers and is a different material than the first and second conductive layers. The dielectric layer is on the lower electrode. The upper electrode is on the dielectric layer opposite to the lower electrode. The first and second conductive layers can have the same thickness. The chemical barrier layer can be thinner than each of the first and second conductive layers. Related methods are discussed.

摘要:
Integrated circuit capacitors have composite dielectric layers therein. These composite dielectric layers include crystallization inhibiting regions that operate to increase the overall crystallization temperature of the composite dielectric layer. An integrated circuit capacitor includes first and second capacitor electrodes and a capacitor dielectric layer extending between the first and second capacitor electrodes. The capacitor dielectric layer includes a composite of a first dielectric layer extending adjacent the first capacitor electrode, a second dielectric layer extending adjacent the second capacitor electrode and an electrically insulating crystallization inhibiting layer extending between the first and second dielectric layers. The electrically insulating crystallization inhibiting layer is formed of a material having a higher crystallization temperature characteristic relative to the first and second dielectric layers.
