  By combining very low temperature scanning tunneling microscopy and
spectroscopy on a TiN film we have observed a non uniform state comprising of
superconducting (S) and normal (N) areas. The local density of states displays
a spatial dependence between S and N different from the usual proximity effect.
We conclude that mesoscopic fluctuations might play a major role in accordance
with recent theories on superconductor-normal metal quantum transition.
