  • Publication number: 20180122838
    Abstract: 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.

  • Patent number: 8418359
    Abstract: A method for manufacturing a circuit pattern-provided substrate including forming a resist layer on a substrate, forming an opening corresponding to a circuit pattern and having an eaves cross-sectional shape in the resist layer, forming a thin film layer having a portion formed on the substrate in the opening and a portion formed on the resist layer, and removing the resist layer such that the resist layer and the portion of the thin film layer formed on the resist layer are removed from the substrate. The forming of the opening comprises exposing the resist layer with a mask device which changes an exposure amount of the resist layer such that the eaves cross-sectional shape has a space at a boundary between the resist layer and the substrate.

  • Publication number: 20110026236
    Abstract: Disclosed is a glass laminate comprising a thin glass substrate having a first main surface and a second main surface, a supporting glass substrate having a first main surface and a second main surface, and a resin layer and an outer frame layer arranged between the thin glass substrate and the supporting glass substrate. The resin layer is fixed to the first main surface of the supporting glass substrate and is in close contact with the first main surface of the thin glass substrate, while having easy releasability from the first main surface of the thin glass substrate. The outer frame layer surrounds the resin layer on the first main surface of the supporting glass substrate so that the outside air does not come into contact with the resin layer.
