  We consider the quantum vacuum effects of the massless scalar fields that are
non-minimally coupled to the background geometry of a collapsing homogeneous
ball of dust. It is shown that for a definite range of coupling constants,
there are repulsive quantum vacuum effects, capable of stopping the collapse
process inside the black hole and precluding the formation of singularity. The
final fate of the collapse will be a black hole with no singularity, inside
which the matter stays balanced. The density of the final static matter will be
close to the Planck density. We show that the largest possible radius of the
stable static ball inside a black hole with Schwarzschild mass $M$ is given by
${{\left( \frac{1}{90\pi }\frac{M}{{{m}_{p}}} \right)}^{\frac{1}{3}}}{{\ell
}_{p}}$. If the black hole undergoes Hawking radiation, the final state will be
an extremal quantum-corrected black hole, with zero temperature, with a remnant
of matter inside. We show that the resolution of singularity is not disrupted
under Hawking radiation.
