    摘要: A method of fabricating a uniformly wrinkled capacitor lower electrode without the need to perform a high-temperature heat treatment and a method of fabricating a capacitor including the uniformly wrinkled capacitor lower electrode are provided. A first conductive layer is formed. Then, a second conductive layer including about 20% to about 50% of impurities is formed on the first conductive layer. Next, at least some of the impurities are exhausted from the second conductive layer by heat treating the second conductive layer. A surface of the second conductive layer is wrinkled due to the exhaustion of the impurities from the second conductive layer. A dielectric layer and an upper capacitor electrode may then be formed.

    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: In a method of manufacturing a capacitor by performing a multi-stepped wet treatment on the surface of a metal electrode, a lower metal electrode of a capacitor is formed, and a primary wet treatment is performed on the surface of the lower metal electrode to remove unwanted surface oxides that may exist on the surface of the lower metal electrode. A secondary wet treatment is then performed on the surface of the lower metal electrode by using a different etchant than the etchant used in the primary wet treatment, in order to remove unwanted surface organic materials that may exist on the surface of the lower metal electrode. A dielectric layer is then formed on the lower metal electrode using a high-k dielectric material. An upper metal electrode is formed on the dielectric layer.

    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.
