The present invention provides a pellicle frame (excluding a pellicle frame containing quartz glass) having a rectangular shape, which has: one end face to be provided with an adhesive layer capable of adhering to a photomask; and the other end face for supporting a pellicle film. The one end face has an amount of twist ?d of 10 ?m or less. The amount of twist ?d of the one end face indicates the maximum value of the distance between a virtual plane that passes through three points, of four points at four corners of the one end face, and one remaining point.

A pellicle for a photomask, a reticle including the same, and an exposure apparatus for lithography are provided. The pellicle may include a pellicle membrane and a passivation member. The pellicle membrane may include a carbon-based material having defects. The passivation member may cover the defects of the carbon-based material. The passivation member may include an inorganic material. The passivation member may be disposed on one or two surfaces of the pellicle membrane. The pellicle for the photomask may be applied to extreme ultraviolet (EUV) lithography.

Disclosed are a pellicle for an extreme ultraviolet (EUV) lithography, which is excellent in transmittance of EUV exposure light and mechanical strength, and a method of fabricating the same. The pellicle includes a support layer pattern; a buried oxide layer pattern formed on the support layer pattern; and a pellicle layer provided being supported by the buried oxide layer pattern. The pellicle may further include a reinforcement layer for reinforcing the mechanical strength of the pellicle layer, an auxiliary layer for additionally supplementing the mechanical strength of the reinforcement layer, and a heat dissipation layer for dissipating heat of the pellicle layer.
