There is disclosed a mask supporting device comprising a chuck mechanism for supporting a mask substrate provided with a rectangular window in which a mask pattern is formed, and a frame for reinforcing the mask substrate, and a mechanism for applying, to said frame of the mask, loads from mutually orthogonal directions. The mechanism for applying loads includes a fixed reference contacting two positions on the external periphery of the mask frame and two pressing mechanism for applying loads to the mask frame from two directions respectively opposed to the two contact positions.

A method of producing an X-ray mask includes a step of forming a mask pattern on a mask substrate having an amount of warp, and a step of bonding the mask substrate to a mask frame. In both steps, the mask substrate maintains a shape obtained due to the amount of warp. Since the mask substrate is fixed to the mask frame in a warped state, distortion is not produced in the mask pattern. As a result, an X-ray mask, which is suitable for very precise exposure, is provided.
摘要:
A method of making an X-ray mask structure having an X-ray absorber in a desired pattern on the surface of a support film held by a frame. The method includes a step of patterning the X-ray absorber, including a drawing step that utilizes charged particles, and a step of thereafter providing the frame with a magnetic member. The frame and the support film each include a non-magnetic material.

A manufacturing method of manufacturing an image display device having a wiring and a display element electrically connected to the wiring, comprises a step of dividing a device having the wiring and a substrate holding the wiring, at a predetermined division position, and the dividing step further comprises a step of dividing the substrate at the predetermined division position, and a step of dividing the wiring at the predetermined division position. The step of dividing the wiring is executed in a method different from a method in the step of dividing the substrate. Thus, the device constituting the image display device can be suitably divided.
