  We analyze, in the framework of AdS/CFT correspondence, the gauge theory
phase structure that are supposed to be dual to the recently found
non-supersymmetric dilatonic deformations to AdS_5 X S^5 in type IIB string
theory. Analyzing the probe D7-brane dynamics in the backgrounds of our
interest, which corresponds to the fundamental N=2 hypermultiplet, we show that
the chiral bi-fermion condensation responsible for spontaneous chiral symmetry
breaking is not logically related to the phenomenon of confinement.
