CYLINDRICAL MAGNETIC LEVITATION STAGE

摘要

PURPOSE: A cylindrical magnetic levitation stage is provided to directly process a pattern of nanometer size on the cylinder surface of large size by actively controlling the location of a cylinder with an error of the nanometer size. CONSTITUTION: A cylinder movable unit is composed of a rotary cylinder movable unit(110b) and a linear transfer cylinder movable unit(110a). A base unit supports the cylinder movable unit which can be rotated without contact. The base unit comprises electromagnet arrangement bodies(122a, 123a, 122b, 123b). A horizontal magnetic levitation auxiliary unit(140) controls the horizontal direction location of a cylinder mold and the cylinder movable unit. The horizontal magnetic levitation auxiliary unit comprises an electromagnet arrangement body(141).
