Patent ID: 7098503

Claim:
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 2 at a flow rate of about 50 sccm into a reaction chamber; flowing a platinum precursor comprising MeCpPt(Me) 3 into the reaction chamber using carrier gas flowing through a bubbler at a pressure of about 6 Torr and a flow rate of about 5 sccm; 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.
