  • Surface-protection method during etching
    Patent number: 5300172
    Abstract: There is disclosed a surface-protection method during chemical etching of a plate material, which comprises sticking a radiation-curable adhesive tape onto the area of plate material where etching should not be effected, and after the radiation-curable adhesive layer is cured with irradiation of radiation, subjecting said plate material to a chemical etching treatment.
    Type: Grant

  • Radiation-curable adhesive tape
    Patent number: 5281473
    Abstract: There is provided a radiation-curable adhesive tape comprising a radiation-curable adhesive layer which is formed on a radiation transmitting-substrate. The radiation-curable adhesive layer is composed of an acrylic adhesive and radiation-curable compound having carbon-carbon double bonds. The radiation-curable tape can be used preferably in processing steps for the production of semiconductor wafer, ceramics and glass employing a direct picking-up system.
