Abstract:
1. A sealant laminated composite for collectively sealing a semiconductor devices mounting surface of a substrate on which semiconductor devices are mounted or a semiconductor devices forming surface of a wafer on which semiconductor devices are formed, comprising: a support wafer; and an uncured resin layer constituted of an uncured thermosetting resin formed on one side of the support wafer, wherein the support wafer is a resin-impregnated fiber base material constituted of a fiber base material impregnated with a thermosetting resin composition that is semi-cured or cured, the uncured resin layer is constituted of an uncured thermosetting resin composition formed on one side of the resin-impregnated fiber base material with a thickness more than 200 μm and 2000 μm or less, and at least one of the thermosetting resin composition that is impregnated in the fiber base material and the thermosetting resin composition that constitutes the uncured resin layer contains an ion trapping agent.
