    摘要: A method for manufacturing a capacitor of a semiconductor memory device by a two-step thermal treatment is provided. A lower electrode is formed on a semiconductor substrate. A dielectric layer is formed over the lower electrode. An upper electrode formed of a noble metal is formed over the dielectric layer. The resultant having the upper electrode undergoes a first thermal treatment under a first atmosphere including oxygen at a first temperature which is selected to be within a range of 200-600° C., which is lower than the oxidation temperature of the upper electrode. The first thermally treated resultant undergoes a second thermal treatment under a second atmosphere without oxygen at a second temperature which is selected to be within a range of 300-900° C., which is higher than the first temperature.

    摘要: A method for manufacturing a capacitor of a semiconductor memory device by controlling thermal budgets is provided. In the method for manufacturing a capacitor of a semiconductor memory device, a lower electrode is formed on a semiconductor substrate. The lower electrode is heat-treated with a first thermal budget. A dielectric layer is formed on the heat-treated lower electrode. The dielectric layer is crystallized by heat-treating the dielectric layer with a second thermal budget which is smaller than the first thermal budget.

    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.
