Abstract

The invention discloses an anisotropic conductive film composition comprising a binding agent containing at least one of polyester type polyurethane resin, polyurethane acrylate resin, and carbamic acid ester resin; ethylene-acetic acid vinyl ester copolymer; materials capable of free radical polymerization containing tricyclodecane dimethanol diacrylate or tricyclodecane dimethanol dimethyl methacrylate; and organic particles. To be specific, the invention relates to a resin composition used for connection of the circuit and a film, which is provided with an extension rate in a range from 10 to 100% after the solidification and has no obvious retraction and expansion in the connection structure. The reliability of the electric connection under the high temperature and high humidity condition can be reduced. The invention also provides a semiconductor device containing the above mentioned anisotropic conductive film.

Description

technical field [0001] The present invention relates to an anisotropic conductive film composition, an anisotropic conductive film produced from the composition, and a semiconductor device. More specifically, the present invention relates to an anisotropic conductive film composition comprising: a polyester urethane resin, a urethane acrylate resin, and a urethane resin other than the polyester urethane resin and the urethane acrylate resin A binder of at least one of: an ethylene-vinyl acetate copolymer; a radically polymerizable material comprising tricyclodecane dimethanol diacrylate or tricyclodecane dimethanol dimethacrylate and organic particles. In particular, the present invention relates to a resin composition and a film for connecting circuits, which have an elongation of 10% to 100% after curing without significant shrinkage and expansion in the connection structure, thereby preventing electrical discharge under high temperature and high humidity. The reliability o...
