  We propose a new type of K\"ahler moduli stabilization mechanisms in type IIB
superstring theory on Calabi-Yau manifolds with the positive Euler number. The
overall K\"ahler modulus can be perturbatively stabilized by radiative
corrections due to sparticles. Its minimum is the anti-de Sitter vacuum, where
supersymmetry is broken. We can uplift it to the de Sitter vacuum by
introducing anti-D-branes, keeping the modulus stabilized. Although our
numerical results depend on the choice of the cutoff scale and degeneracies of
sparticles, at any rate there exist the parameter spaces where the masses of
Kaluza-Klein and stringy modes are larger than the cutoff scale. Furthermore,
this stabilization scenario predicts an ultralight axion.
