Abstract: PURPOSE:To make it possible to facilitate the lift of a polishing plate in the polishing device of a semi-conductor wafer, by providing a leak valve mechanism which is opened by negative pressure from the contact surface with a workpiece, on the polishing plate. CONSTITUTION:A wafer 2 is holded on a polishing plate 4 by vacuum absorption force through the vacuum suction passage 5 of the polishing plate and the polishing plate is lowered to a surface plate 1, the wafer 2 is directed downwards, then the vacuum absorption force is released. Further, with adhesive material 6 dropped from a nozzle 7 to the surface plate 1, the surface plate 1 and the polishing plate 4 are rotated with the predetermined speed respectively for performing a mirror surface polishing. After finishing the polishing, the wafer 2 is again absorbed by the vacuum suction passage 5. In this case, as the pressure of the space 8 between the polishing plate 4 and the surface plate 1 becomes lower than air pressure around the polishing plate 4, the valve body 14 of the leak valve mechanism 9 is opened so that the air pressure is invaded from the passage 13 of a inserting part 11 through an air passage 10. Thus, the pressure becomes equal to the air pressure, thereby it is possible to lift the polishing plate 4 and the wafer 2.

CONSTITUTION:Tapered portions 15, 15, on which electrodes 4a, 4b are not coated, are formed on peripheries of opposite edge faces 4t, 4t. In the tapered portions 15, 15, even when electrode material supply surfaces of a machining device come close to a positive characteristic thermistor element 4 from opposite sides of the same and make contact with the opposite end surfaces 4t, 4t of the same, the peripheries 15, 15 of the opposite edge faces 4t, 4t are separated away by taper fractions from the electrode material supply surfaces to prevent the coating of the electrode material with ease. Accordingly, there is unnecessary a mounting process of a coating prevention cover for the peripheries 15, 15, thereby permitting a short-circuiting prevention structure between the opposite electrodes 4a, 4b to be formed simply. In the positive temperature coefficient thermistor device, there is elongated a migration advancing distance of the silver material of the electrodes 4a, 4b on the thermistor element 4 by a fraction of the separation distance to prevent any short-circuiting failure from occurring between both electrodes 4a, 4b.
