This ARL formation occurs after the capacitor specific process steps, but prior to the masking used for defining the lower electrodes.

  • Publication number: 20120262835
    Abstract: A method for fabricating a dynamic random access memory (DRAM) capacitor stack is disclosed wherein the stack includes a first electrode, a dielectric layer, and a second electrode. The first electrode is formed from a conductive binary metal compound and the conductive binary metal compound is annealed in a reducing atmosphere to promote the formation of a desired crystal structure. The binary metal compound may be a metal oxide. Annealing the metal oxide (i.e. molybdenum oxide) in a reducing atmosphere may result in the formation of a first electrode material (i.e. MoO2) with a rutile-phase crystal structure. This facilitates the formation of the rutile-phase crystal structure when TiO2 is used as the dielectric layer. The rutile-phase of TiO2 has a higher k value than the other possible crystal structures of TiO2 resulting in improved performance of the DRAM capacitor.
