Abstract:
An electronic beam proximity exposure apparatus, comprising:an electron beam proximity exposure section which exposes a pattern corresponding to an aperture of a mask on a surface of an object with an electron beam that has passed through the aperture of the mask, the mask being disposed in proximity to the surface of the object; a detachable wafer cassette; a shielding mechanism; a vacuum chamber, the electron beam proximity exposure section being located in said vacuum chamber; a mask inspecting section which inspects the mask; and a mask carrying mechanism which carries the mask between the electron beam proximity exposure section and the mask inspecting section, wherein said wafer cassette is detachably connected to said vacuum chamber through said shielding mechanism; and wherein the electron beam proximity exposure section, the mask inspecting section and the mask carrying mechanism are communicated with one another through a common vacuum path which enables the mask to be carried in a vacuum condition between the electron beam proximity exposure section and the mask inspecting section.
