    摘要: A pellicle for a mask or substrate including a frame having one end surface and another end surface and a membrane extended over the frame on the one end surface side. A channel is formed in the other end surface of the frame. The channel is filled with a layer of a tackifier capable of expanding upon heating and/or light irradiation such that the tackifier layer does not protrude outward beyond the other end surface of the frame in an unexpanded state, but protrudes outward beyond the other end surface of the frame when expanded. No liner is attached to the tackifier layer.

    摘要: Proposed is an improved frame-supported pellicle, which is an integral body consisting of a rigid frame, a transparent plastic resin film adhesively bonded to one end surface of the frame in a slack-free fashion and a layer of a pressure-sensitive adhesive on the other end surface of the frame. The improvement consists in the use of a specific pressure-sensitive adhesive capable of being imparted with a greatly decreased bonding strength when it is heated at a temperature higher than a critical temperature or irradiated with UV light in a dose exceeding a critical dose so as to facilitate demounting of the frame-supported pellicle from a photomask on which the pellicle is mounted when it is to be replaced with a new pellicle without leaving any fragments of the adhesive adherent to the photomask surface.

    摘要: An improvement is proposed in the method for the preparation of a frame-supported pellicle involving a step in which a resin film for the pellicle membrane formed on the surface of a substrate plate by the solution casting method is adhesively bonded to a rigid pellicle frame and then the substrate plate is removed by separating from the resin film by pulling the substrate and the frame apart in a gaseous atmosphere of which the relative humidity is 80% or higher in contrast to the conventional procedures in which this step is conducted either in water or in a gaseous atmosphere of an air-conditioned clean room having a relative humidity never exceeding 60%. By virtue of this unique procedure, an outstandingly small number of dust particles are deposited on the pellicle membrane obtained by the removal of the substrate therefrom along with an advantage of very smooth and easy removal of the substrate not to cause slack or rupture of the membrane.

    摘要: Disclosed is an X-ray transmitting frame-supported membrane of silicon nitride suitable as a mask blank of an X-ray lithographic mask having outstandingly high resistance against irradiation with high-energy radiations and high transmission of light of a wavelength of 633 nm. These very desirable properties are obtained as a consequence of the extremely low content, i.e. 1.0 atomic % or less, of hydrogen in the silicon nitride, which can be achieved as a result of the specific preparation procedure by the CVD method in which the reactant gases are silane or disilane and ammonia in a specified mixing ratio to be reacted under a specified pressure and at a specified temperature.

    摘要: The inventive method provides a membrane for X-ray lithography compositely composed of silicon carbide and silicon nitride having high performance in respect of stability against high energy beam irradiation and transparency to visible light. The method comprises depositing a composite film of a specified SiC:Si.sub.3 N.sub.4 molar proportion by sputtering on a silicon wafer as the substrate under such conditions that the thus deposited film is under a compressively stressed state, annealing the substrate bearing the composite film deposited thereon at a specified temperature so as to bring the composite film under a tensile internal stress and then removing the substrate by etching leaving a frame portion.
