摘要: A carrier substrate to be used, when manufacturing a member for an electronic device on a surface of a substrate, by being bonded to the substrate, includes at least a first glass substrate. The first glass substrate has a compaction described below of 80 ppm or less. Compaction is a shrinkage in a case of subjecting the first glass substrate to a temperature raising from a room temperature at 100° C./hour and to a heat treatment at 600° C. for 80 minutes, and then to a cooling to the room temperature at 100° C./hour.

摘要: To provide a process for producing a film excellent in water vapor barrier property, tensile elongations, and transparency. A resin material containing polychlorotrifluoroethylene (PCTFE) is melted and extruded into a film from an extrusion die, the extruded product is brought into contact with a cooling roll having a surface temperature of at most 120° C. in a state such that the surface temperature of the extruded product is higher than the crystallization temperature of PCTFE to form a film web, and the film web is subjected to heat treatment at from 80 to 200° C. to obtain a film.

摘要: To provide a film made of polychlorotrifluoroethylene (PCTFE), of which a laminate with other layer is less likely to curl when subjected to drawing.
A film comprising PCTFE, having thermal shrinkage rates within ±1.2% in MD and in TD when heated at 140° C. for 30 minutes and then cooled to 25° C., based on the dimension at 25° C.
