Problems solved by technology

That is, since the adhesive force of the die-bonding film is weak, peeling between the chip and the bonding film is easy to occur, and the moisture resistance of the organic film is also weak, so the package cracking is easy to occur

Abstract

The invention provides an epoxy resin composition for a multi-chip package. The epoxy resin composition comprises an epoxy resin, a solidifying agent, a solidification promoting agent, a coupling agent and an inorganic filling agent. The invention is characterized in that the coupling agent includes a hydroxide radical siloxane resin comprising an alkyl. The epoxy resin composition has good property in the formation aspect at the same time of having excellent reliability.

Description

technical field [0001] The present invention relates to an epoxy resin composition for multi-chip packaging, and relates to an epoxy resin composition having good adhesion properties to metal components, moisture resistance properties, crack resistance at high temperature and mechanical properties, and excellent reliability and formability. Background technique [0002] Recently, the integration level of semiconductor elements has been increasing, and at the same time, the miniaturization of wiring, the enlargement of elements, and the multilayer wiring have rapidly progressed. On the other hand, from the viewpoint of high-density mounting on printed circuit boards, that is, surface mounting, packages (Packages) for protecting semiconductor elements from the external environment are rapidly progressing toward miniaturization and thinning. [0003] In a resin-sealed semiconductor device in which a large semiconductor element is sealed in a small, thin package as described abo...
