    Abstract: There is provided a method for processing an inner wall surface of a micro vacancy, capable of reliably etching and cleaning even if the hole provided to the substrate to be processed is narrow and deep. The substrate has a surface on which a processing solution is to be applied and a micro vacancy with an opening on the surface. An aspect ratio (l/r) of the micro vacancy being at least 5, or the aspect ratio being less than 5 and a ratio (V/S) of a micro vacancy volume (V) to a surface area of the opening (S) being at least 3. The substrate is arranged in a processing space. Next, the processing space is depressurized, and subsequently the processing solution is introduced into the processing space so as to process the inner wall surface of the micro vacancy.

    Abstract: Provided is a neutron shielding material having good light transparency and excellent shielding performance against thermal neutron rays, and a method for producing the same. A neutron shielding material according to the present invention includes a light transmitting material and a boron compound enriched in a boron isotope having a mass number of 10, the neutron shielding material being formed of a molded product having light transparency. Shielding performance against thermal neutron rays is improved by containing a boron compound enriched in a boron isotope having a mass number of 10. As a result, the neutron shielding material can be widely applied to members requiring visibility and neutron blocking properties.
