The semiconductor memory device includes an interlevel dielectric pattern and
an adhesive pattern, wherein both the interlevel dielectric and adhesive patterns
include a contact hole to expose a semiconductor substrate. The adhesive pattern
sufficiently adheres a lower electrode of a capacitor to the interlevel dielectric
pattern, and thus prevents damage to the interlevel dielectric pattern during the
formation of the capacitor. A conductive plug is disposed within the contact hole
and may project higher than the top surface of the adhesive pattern. A leakage
current preventive pattern is formed on top of the adhesive pattern and prevents
a capacitor dielectric layer from directly contacting the plug to prevent occurrences
of leakage current. A lower electrode of a capacitor electrically connected to
the plug is formed on the plug.
