摘要： The purpose of the present disclosure is to provide a pellicle that has an adhesive layer having good flatness, and a method for producing the pellicle with good reproducibility. Said purpose is achieved by a pellicle having: a pellicle frame; a pellicle film provided so as to be stretched on one end surface of the pellicle frame; and an adhesive layer provided on the other end surface of the pellicle frame. The adhesive layer contains a cured product of a resin composition containing a curable polymer (A), and a curing agent (B1) and a curing agent (B2). The curing agent (B1) and the curing agent (B2) have different curing conditions.

摘要： The disclosure addresses provision of a pellicle demounting method having excellent property with respect to reduction of contamination of a photomask. A method of demounting a pellicle, the method is provided which includes: providing a stack including a photomask, a pellicle frame, and a pellicle film that are arranged in this order; providing an electrode; and a demounting step including disposing the stack and the electrode such that the pellicle film in the stack and the electrode face each other, and applying a voltage to the electrode to generate an electrostatic attractive force, which attracts the pellicle film in a direction toward the electrode, thereby demounting the pellicle film from the photomask in the stack.

摘要： A sensor includes a body member, a volume change body, and a detection member. The body member has a flat plate-like shape, a first end in a first direction being supported, and a storage space opening at at least one of both end faces in a thickness direction. The volume change body, whose volume changes depending on an amount of a target, is supported by the body member so that at least a part of the volume change body is stored in the storage space. The detection member is in contact with a second end in the first direction of the body member, and detects stress caused by the change in the volume of the volume change body.
