  We have fabricated thin films of FeTe$_{1-x}$Se$_x$ using a scotch-tape
method. The superconductivities of the thin films are different from each other
although these films were fabricated from the same bulk sample. The result
clearly presents the inhomogeneous superconductivity in FeTe$_{1-x}$Se$_x$. The
difference comes from inhomogeneity due to the excess Fe concentration. The
resistivity of a thin film with low excess Fe shows good superconductivity with
the sharp superconducting-transition width and more isotropic
superconductivity.
