Abstract:
1. A capacitor comprising: a first capacitor electrode over a monocrystalline silicon substrate; a second capacitor electrode; a dielectric layer between the first and second capacitor electrodes; and at least one of the first and second capacitor electrodes comprising hemispherical grain platinum formed by a process comprising: flowing an oxidizing gas comprising O flowing a platinum precursor comprising MeCpPt(Me) chemical vapor depositing hemispherical grain platinum from the platinum precursor over the substrate in the presence of the oxidizing gas, the hemispherical grain platinum having a continuous surface characterized by columnar pedestals; and maintaining a temperature and pressure within the reaction chamber at about 215° C. and 5 Torr, respectively, during the depositing.
