Low temperature scanning tunneling microscopy/ scanning tunneling spectroscopy, room temperature atomic force microscopy and X-ray photoelectron spectroscopy of the boron ions implanted into the magnesium substrate were performed in order to get information about the local superconducting behavior of thin MgB_x film. Results confirm the island superconductivity far from the percolation threshold of the bulk superconducting MgB₂ sample.
