    摘要: A pellicle film of a silicon single crystal film and a base substrate supporting the pellicle film are formed of a single substrate using an SOI substrate. The base substrate is provided with an opening whose ratio in area to an exposure region when a pellicle is used on a photomask (an open area ratio) is 60% or more, and provided with a reinforcing frame in a non-exposure region of the base substrate. Since the pellicle film and the base substrate supporting the pellicle film are formed of the single substrate (an integrated structure), and the base substrate is provided with the reinforcing frame, the effect of increased strength is obtained. Moreover, a principal plane of a silicon single crystal film is a crystal plane inclined at 3 to 5° from any lattice plane belonging to {100} planes or {111} planes.

    摘要: A silicon single crystal film having a crystal plane as its principal plane, the crystal plane being inclined at 3 to 5° from any lattice plane belonging to {100} planes or {111} planes is used as a pellicle film. The silicon single crystal having such a crystal plane as its principal plane has effective bond density and Young's modulus thereof which are about 40% to about 50% higher than those of a silicon single crystal with orientation, and therefore a cleavage and crack do not easily occur. Moreover, the silicon single crystal has a high chemical resistance such as hydrofluoric acid resistance, and hardly causes an etch pit and void. Accordingly, the present invention can provide a pellicle comprising a pellicle film for EUV having high transmission, and excellent mechanical and chemical stability, as well as having a high yield, and being practical also in cost.

    摘要: Disclosed is a semiconductor device fabricating method. A substrate is provided thereon with: an inorganic insulating film; a first inorganic sacrifice film stacked on the inorganic insulating film and having components different from those of the inorganic insulating film; a second sacrifice film formed of an inorganic insulative film stacked on the first sacrifice film, wherein a pattern for forming grooves for wiring embedment is formed in the second sacrifice film; and an organic layer including a photoresist film, wherein a pattern for forming holes for wiring embedment is formed in the organic film. According to the present invention, the thickness of the organic layer is set to be greater than the sum of the thicknesses of etch target films, i.e., the insulating film, the first sacrifice film and the second sacrifice film; the etch target films are etched in a selectivity-less manner by using plasma generated from a mixed gas of CF4 gas and CHF3 gas.
