- a pressurized fluid is supplied between the carrier and the film body of the film frame from the pressurized fluid supply means for polishing, and the glass substrate is polished and fixed by the pressure of the pressurized fluid. Since the polishing is performed by pressing against the plate, the pressure applied to each part of the glass substrate becomes uniform, and the glass substrate can be polished flat. Along with this, polishing is not affected by the surface shape of the polishing platen, that is, even if there is some undulation on the surface of the polishing platen, the undulation is not transferred to the glass substrate. It is not necessary to set the precision of the platen, and the cost of the polishing platen can be reduced.
- a preferred film body of the present invention has an airtight holding layer whose outer peripheral portion is in close contact with the carrier and maintains airtightness with the carrier, a predetermined airtight layer that holds the airtight holding layer and can withstand the tension that stretches the film body. Since the glass substrate has a three-layer structure including a strength holding layer having a tensile strength and a smooth layer to which a glass substrate is adhered, the glass substrate can be stably held on the film body, and therefore, the glass substrate can be precisely formed. Can be polished well.
- the material of the strength retaining layer of the membrane is aramid fiber, stainless steel wire mesh, steel wire mesh, carbon fiber, glass fiber, nylon fiber, or a tensile strength equivalent to these materials.

- the present invention is particularly effective for a polishing method and a polishing apparatus for polishing a large area substrate.
- the substrate can be adhered to the film only by pressing the film against the substrate without intervening bubbles between the substrate and the film.
- the presence of air bubbles leads to a decrease in the adhesive strength, and the amount of air bubbles needs to be as small as possible in order to ensure adhesion.
- simply pressing the film against the substrate increases the amount of intervening bubbles due to the high flatness of each. Therefore, as in the present invention, The film is pressed with a roller, and the film is handled and the bubbles intervening between the film and the substrate are forcibly discharged and adhered. Thereby, even if the substrate has a large area, the substrate can be securely and firmly attached to the film body.

- a polishing method and apparatus for polishing a large area substrate By fitting a plurality of pins implanted in the membrane frame into a plurality of holes formed in the carrier, when positioning and connecting the membrane frame and the carrier, in the case of a small membrane frame, the pin mounting accuracy is reduced. Since all the pins are easily ejected, all the pins can be fitted into the holes even if all the pins are fixed to the membrane frame. On the other hand, in the case of a large film frame to which a large-area substrate is stuck, it is difficult to obtain the pin mounting accuracy, and when all the pins are fixed, the pins may be fitted into the holes. It is difficult.
- the mounting error can be absorbed by the amount of play, so that all pins can be fitted.
- all the pins are loose, positioning is not possible because the film frame is loose with respect to the carrier, and the pins also have a function to resist the shearing force applied from the polishing plate during polishing. They may not be able to withstand the shear forces.
- a predetermined number of pins out of a plurality of pins are movably attached to the membrane frame, so that the mounting errors are absorbed by these pins, and the remaining pins are fixed to the membrane frame. Then, the remaining pins were used to oppose the shear force applied from the polishing platen. Thereby, the large film frame can be positioned with respect to the carrier and can be stably connected.
