Title:
EPOXY MOLDING COMPOUND AND METHOD FOR PREPARING SAME, SEMICONDUCTOR PACKAGING STRUCTURE, AND ELECTRONIC APPARATUS
Document Type and Number:
WIPO Patent Application WO/2023/245413
Kind Code:
A1
Abstract:
Provided is an epoxy molding compound, comprising an epoxy resin pretreated by a stress absorbent, which is a mixture obtained by melt blending of a stress absorbent and an epoxy resin, the stress absorbent being a styrene-butadiene copolymer or a derivative thereof; a phenolic resin pretreated by an inorganic nanofiller, which is a mixture obtained by melt blending of a phenolic resin and an inorganic nanofiller; an inorganic microfiller; and a curing accelerator. The epoxy molding compound comprises 5-15 parts by weight of the epoxy resin, 0.1-5 parts by weight of the stress absorbent, 0.5-10 parts by weight of the inorganic nanofiller, 5-8 parts by weight of the phenolic resin, 65-90 parts by weight of the inorganic nanofiller and the inorganic microfiller, and 0.1-1.5 parts by weight of the curing accelerator. The present application further provides a method for preparing the epoxy molding compound, a semiconductor packaging structure, and an electronic apparatus. The pretreatment of the inorganic nanofiller and the stress absorbent can further reduce the modulus of the epoxy molding compound.
