  • Publication number: 20230407127
    Abstract: A coating agent has: a film-forming component containing an organosilicon compound having a radical polymerizable functional group and an alkoxysilyl group; and a film-curing component composed so that a base and a radical can be generated on irradiation with ultraviolet light. The film-curing component includes a nonionic photobase generator having no ionic bond in the molecular structure. The content of the nonionic photobase generator is 0.1 parts by mass or more and 50 parts by mass or less, based on 100 parts by mass of the organosilicon compound.

  • Publication number: 20190016932
    Abstract: A laminate includes a resin substrate, an intermediate layer disposed on a surface of the resin substrate, and a silicon oxide layer disposed on a surface of the intermediate layer. The intermediate layer is formed by curing a composition containing a Si-free compound containing a (meth)acrylic group and a siloxane compound containing a (meth)acrylic group. A concentration of Si is higher on a silicon oxide layer side than a concentration of Si on a resin substrate side in the intermediate layer.

  • Patent number: 7662699
    Abstract: An object is to provide a technology capable of improving a manufacturing yield of semiconductor devices by preventing scattering of irregular-shaped scraps formed at the time of dicing. To achieve the above object, for dicing lines, by which an irregular-shaped outer periphery may possibly be cut off, among a plurality of dicing lines, formation of the dicing lines starts from an outside of a semiconductor wafer, and after the semiconductor wafer is cut off partway, formation of the dicing lines is ended before reaching the irregular-shaped outer periphery formed on a outer periphery of the semiconductor wafer. For other dicing lines, formation of the dicing lines starts from the outside of the semiconductor wafer, and after the semiconductor wafer is cut off, is ended outside the semiconductor wafer.
