  We study the confinement/deconfinement transition of QCD matter for a
quark-gluon plasma at finite density using AdS/QCD duality. In order to
determine the critical temperature and its dependence on the quark chemical
potential, the semi-classical Hawking-Page approach is considered for a charged
AdS black hole. The result obtained is consistent with the QCD phase diagram,
with the critical temperature decreasing as the chemical potential increases.
Using the soft wall holographic model, the value of quark density in which the
phase transition occurs at zero temperature is estimated. For higher densities
the QCD matter is deconfined, independent of the temperature.
