Abstract: PURPOSE: An electrode structure for a semiconductor memory device is provided to be used as a lower electrode and a barrier layer for a stack of a dielectric layer and a polysilicon layer, by maintaining a stable interface state at a high temperature, and by controlling a formation of a silicide layer. CONSTITUTION: An electrode structure for a semiconductor memory device comprises a silicon-series material(21), a ruthenium layer(23) and a platinum layer(25). The silicon-series material is polysilicon, oxidation silicon or silicon. The ruthenium layer(Ru) is evaporated on the surface of the silicon-series material. The platinum layer(Pt) is evaporated on the surface of the ruthenium layer.
