Abstract

The adhesive composition for semiconductors of the present invention is characterized in that two exothermic peaks appear at 65-350 DEG C, of which a first exothermic peak appears at 65-185 DEG C and a second exothermic peak appears at 155-350 DEG C, wherein less than 10% of the composition, which is cured at 150 DEG C for 10 minutes, cured at 150 DEG C for 30 minutes, and then molded at 175 DEG C for 60 seconds, consists of voids. The adhesive composition for semiconductors is characterized by enabling a reduction in and the skipping of semi-curing steps, which would be necessary to perform after bonding the same type of chips.

Description

technical field [0001] The present invention relates to an adhesive composition for semiconductors and an adhesive film comprising the same. More specifically, the present invention relates to adhesive compositions for semiconductors that allow shortening or omission of the semi-curing process that must be included after chip bonding and still provide curing after various processes after chip bonding rate, thereby facilitating the removal of voids in EMC molding. The invention also relates to adhesive films comprising it. Background technique [0002] In order to realize a semiconductor device with high capacity, a qualitative high integration method of increasing the number of cells per unit area and a quantitative packaging method of depositing a plurality of chips to increase capacity are used. [0003] As a packaging method, multi-chip packaging (MCP) is generally used in which multiple chips are deposited using an adhesive and the upper and lower chips are electricall...
