Conventionally, as described in JP-A No. 60-141869, in order to deposit metal atoms on the surface of a sample (strip steel), the deposited metal substance was heated and evaporated using an electron beam or a heating coil. Ion mixing is performed by implanting ions from a placed ion source, and in the conventional method, it was necessary to install separate power supplies for heating the deposited metal and for ion implantation, resulting in a large vacuum chamber and a large-scale film forming apparatus. However, the disadvantage was that the price of the device was high.

A sample holder 3 rotated by a rotational drive mechanism outside the chamber 2 is installed in a vacuum chamber 2 heated to a temperature of 10 -7 Torr), and a sample 4 is fixed in close contact with the sample holder 3. Ion implantation is performed by accelerating ions toward the sample 4 from an ion source 5 which is controlled by a power supply device 6 and is provided below in the vacuum chamber 2 facing the sample 4 . On the other hand, metal atoms are deposited on the surface of the sample 4 by irradiating the surface of the deposited metal 10 with an electron beam from an electron beam generator 7 provided below in the vacuum chamber 2 using an electron beam deflection electromagnet 8. This is done by heating the surface of the deposited metal 10 to evaporate metal atoms toward the sample 4. The energy of the electron beam is controlled by a vapor deposition power supply 9. That is, the present invention eliminates the need for the electron beam generator 7, electromagnet 8, and vapor deposition power supply 9 shown in FIG.
