A stabilizing solution for treating photoresist patterns and methods of
preventing profile abnormalities, toppling and resist footing are
disclosed. The stabilizing solution comprises a non-volatile component,
such as non-volatile particles or polymers, which is applied after the
photoresist material has been developed. By treating the photoresist with
the solution containing a non-volatile component after developing but
before drying, the non-volatile component fills the space between
adjacent resist patterns and remains on the substrate during drying. The
non-volatile component provides structural and mechanical support for the
resist to prevent deformation or collapse by liquid surface tension
forces.
