A general analysis of fermion pairing at finite temperature and density between different species with mismatched Fermi surfaces is presented. Very different from the temperature effect of the BCS phase, the recently found breached pairing phase resulted from the density difference of the two species lying in a region with calabashlike shape in the T\ensuremath-\ensuremathμ plane, and the most probable temperature for the new phase's creation is finite but not zero.
