    • PROBLEM TO BE SOLVED: To provide a pressure-sensitive adhesive tape for producing an electronic component, and more specifically, to provide a pressure-sensitive adhesive tape for production, in which pressure-sensitive adhesion is expressed only during a thermal lamination step, although a pressure-sensitive adhesive layer is not pressure-sensitive adhesive at room temperature, and consequently with which lamination on a lead frame is enabled, which has improved thermal resistance with regard to thermal history due to exposure of the pressure-sensitive adhesive tape during a production process of a semiconductor apparatus, owing to formation of a partial interpenetration reticular structure caused by additional photo-curing of the pressure-sensitive adhesive layer, which is useful for reliability improvement of a device during production of the semiconductor apparatus, and which can prevent leakage of an encapsulation material and can prevent a transfer of a pressure-sensitive adhesive to the lead frame or to the encapsulation material in removing the tape after completion of the process.SOLUTION: A pressure-sensitive adhesive tape for producing an electronic component includes a thermal-resistant substrate, a pressure-sensitive adhesive layer formed by applying a pressure-sensitive adhesive composition to the thermal-resistant substrate, the pressure-sensitive adhesive composition includes a phenoxy resin, a thermal curing agent, an energy ray-curable acrylic resin, and a photoinitiator, and the pressure-sensitive adhesive layer is cured by heat and an energy ray.
    • 要解决的问题:提供一种用于制造电子部件的压敏粘合带,更具体地说,提供一种仅在热层压步骤中仅表达压敏粘合力的生产用粘合带,尽管 压敏粘合剂层在室温下不是压敏粘合剂,因此能够在引线框架上进行层压,其具有改善的耐热性,这是由于粘合带在 由于形成由压敏粘合剂层的附加光固化引起的部分互穿网状结构的半导体装置的制造过程,这对于半导体装置的制造期间的装置的可靠性改善是有用的,并且可以防止 封装材料的泄漏并且可以防止压敏粘合剂的转移 e在引线框架或封装材料之后,在完成工艺之后去除胶带。解决方案:用于制造电子部件的压敏粘合带包括耐热基材,通过涂布形成的压敏粘合剂层 压敏粘合剂组合物包含苯氧基树脂,热固化剂,能量射线固化丙烯酸树脂和光引发剂,并且粘合剂层通过 热和能量射线。
