  New types of confinement phase emerge as singular SCFT's appearing as
infrared-fixed-points of N=2 supersymmetric QCD (SQCD) are perturbed by an N=1
adjoint mass term. Based on a recent remarkable work on infrared-fixed-point
SCFT of highest criticalities by Gaiotto, Seiberg and Tachikawa, we discuss
physics of certain confining systems in SU(N), USp(2N) or SO(N) gauge theories.
These show features different from a straightforward dual superconductivity
picture of confinement a' la 't Hooft and Mandelstam, which might suggest a new
venue in exploring the quark confinement mechanism in the real-world QCD.
