Abstract

PURPOSE:To prevent the release of dust to the inner side of the pellicle at the time of sticking the pellicle to a reticule, mask, etc., by providing a dust preventive film on the inner side of an adhesive agent. CONSTITUTION:The dust preventive film 2 stuck to the adhesive agent 1c is provided on the inner side of a frame 1b over the entire circumference on the inner side of the frame 1b. The thickness of the adhesive agent 1c decreases slightly when this pellicle 1 is pressed to the front surface of the mask 3 and is stuck by the adhesive agent 1c. The adhesive agent 1c and the side face of the dust preventive film 2 are then brought into contact with the surface of the mask 3 and the size of the contact part between the film 2 and the frame 1b is increased by as much as the decreased component of the thickness of the adhesive agent 1c. The sticking of the dust released from the adhesive agent 1c to the inner side of the pellicle onto the surface of the mask 3 or into the pellicle 1 is prevented in this way.

As shown in FIG. 3, when attaching such a pellicle 11 to the surface of the mask 3, the frame llb is attached to the mask 3.
When pressed against the surface of the adhesive 11c, the thickness of the adhesive 11c becomes thinner.
At that time, the gob ξ contained in the adhesive 11c is ejected inwardly and outwardly, and the inwardly ejected dust adheres to the surface of the mask 30 and the inside of the pellicle 1l, and this gob ξ is exposed to the semiconductor during the exposure process. This is transferred to the resist 1/film formed on the surface of the substrate, causing a failure that causes defects in semiconductor elements formed on the semiconductor substrate.
