In a semiconductor device manufacturing process, when a pattern is transferred onto a wafer by a projection means using a stepper or an aligner, a reticle or a mask is used as a transfer master. In this case, foreign matter is attached to the reticle or the mask. If this occurs, the foreign matter is transferred and a defect is caused in the transfer pattern, resulting in a defect.

Therefore, it is the pellicle that serves to prevent the transfer of the foreign matter by adhering the above-mentioned foreign matter deposited and adhered from the indoor atmosphere or the like to the defocus surface away from the reticle and the mask surface. However, due to the intrusion of foreign matter into the pellicle and the improvement in the resolution of the stepper and aligner, the transfer of foreign matter is continuously desired to be improved.

However, in the conventional pellicle as described above, the pellicle 56 is the reticle substrate 51.
Since the method is adhesively mounted on the upper side by the adhesive material 55, the foreign material 57 caused by the adhesive material 55 that tends to occur during bonding and the foreign material 57 mixed in the atmosphere at the time of bonding are cavities in the pellicle 56. There is a problem that the foreign matter 57 becomes trapped in the portion 58 and these foreign matters 57 are charged and moved during exposure and adhere to the reticle substrate 51, and the adhesion of the foreign matter 57 causes a defect in the transfer pattern. If the pellicle 56 is not completely adhered, the cavity 58 inside the pellicle 56 will be removed through the gap.
Another problem is that the foreign matter 57 enters from the outside atmosphere.

Further, recently, as the resolution of the stepper and the aligner is improved, the foreign matters attached to the pellicle film are also more likely to be projected. However, in the conventional adhesion type pellicle, after the pellicle adhesion, that is, the pellicle. Since it is difficult to clean after mounting, the pellicle mount body with foreign matter of a size projected on the pellicle film dissolves the adhesive resin and peels off the pellicle from the reticle or mask substrate surface. There is also a problem that it is necessary to bond and use such a pellicle, and it takes a lot of time and man-hours to replace the pellicle.

Therefore, according to the present invention, the amount of foreign matter trapped in the cavity of the pellicle during the pellicle mount for fixing the pellicle on the reticle or mask substrate is suppressed as much as possible, and at the same time, the foreign matter entering from the outside after the pellicle mount is mounted. Transferring due to foreign matter adhesion is eliminated, and foreign matter staying in the cavity is prevented from being charged and adhered to the reticle or mask substrate, and the pellicle film contaminated with foreign matter is easily replaced with a clean film. The purpose is to prevent defective defects of the pattern.
