Abstract: In a micro-channel plate, an electron emission film and an ion barrier film formed on a substrate are integrally formed by the same film formation step. In this structure, the electron emission film and the ion barrier film are made as continuous and firm films and the ion barrier film can be made thinner. Since the ion barrier film is formed on the back side of an organic film, the organic film is exposed during removal of the organic film. This prevents the organic film from remaining and thus suppresses degradation of performance of the ion barrier film due to the residual organic film, so as to suppress ion feedback from the micro-channel plate and achieve a sufficient improvement in life characteristics of an image intensifier.

Abstract: In an electron tube, an atomic layer deposition method is used to form an electrical resistance film having a stacked structure of electrically insulating layers and electrically conductive layers or a mixed structure of an electrically insulating material and an electrically conductive material, so as to cover the whole of an inner wall surface and an outer wall surface of a second envelope. By use of the atomic layer deposition method, the firm and fine electrical resistance film with a desired resistance can be formed on an insulation surface, without containing a material such as a binder. When the electrical resistance film is provided with slight electrical conductivity, it can suppress occurrence of withstand voltage failure due to electrification of the insulation surface or the like and realize stability of withstand voltage characteristics.

Abstract: In an electron tube, an electrical resistance film having a stacked structure of electrically insulating layers and electrically conductive layers is formed on holding surfaces of bases in insulating substrates. This electrical resistance film is made as a firm and fine film with a desired resistance by use of an atomic layer deposition method, which can suppress electrification of the bases comprised of an insulating material. This makes it feasible to stably maintain withstand voltage characteristics.
