2. Description of the Related Art A method for observing the concentration distribution of composition elements and the chemical bonding state from the sample surface to several tens of nm or more by a surface analyzer such as X-ray photoelectron spectroscopy (XPS) is a clean sample surface. As a means of producing
An ion sputter etching method is widely used in which sputter etching is performed by irradiating a sample surface with rare gas ions such as ions. Cleaning of the sample surface using such an ion sputter etching method is a useful method that can be relatively easily realized by preparing an ion gun and a gas introduction system in the analyzer.

However, in the ion sputter etching method, ions accelerated at several 100 V to several kV collide with the sample surface to perform etching while physically destroying the sample surface, so that collision of charged particles occurs. There is a problem that the sample surface is damaged due to the increase in roughness of the sample surface, selective sputtering such as oxygen extraction phenomenon, and compound decomposition are remarkable. As a result, the concentration distribution from the surface of the sample to the inside becomes different from the original concentration distribution of the sample. In particular, when it is used as an organic compound (polymer substance) or the like, the chemical bond state and composition of the sample surface may change, which may interfere with accurate analysis.

Therefore, as a method of reducing the damage on the sample surface due to the ion irradiation of the ion sputter etching as described above and acquiring the information about the original concentration distribution and the change in the chemical bond state, the sputter etching method by cooling the sample has already been used. A sample rotating sputter etching method has been developed. Furthermore, a sputter etching method using neutral particles having no electric charge has been newly developed.

Conventionally, in the case of surface-analyzing a sample of an organic compound or the like, the sample is taken out from the surface analyzer, and the surface of the sample is subjected to a surface treatment so as not to change the chemical bonding state and composition, and then returned again. ing. Therefore, unlike conventional ion sputter etching, the sample is not exposed to the atmosphere by connecting it to a surface analyzer, and even if it is an organic compound, it does not change the chemical bond state or composition of the sample surface. An apparatus for performing surface analysis while etching is not yet realized. Therefore, when performing the depth direction analysis, there has been a problem that much labor and time are required for the analysis work.

Moreover, in an X-ray photoelectron spectrometer or the like, the gas used is changed depending on the type of the sample, and the composition of the organic substance does not change due to the plasma of hydrogen, freon, or oxygen, and it is several tens nm / min from the surface compared to the conventional ion sputter etching method. The depth direction analysis can be performed at the above high etching rate.
