Problems solved by technology

[0005] Therefore, as a prior art for adjusting the fluidity of a layer containing conductive particles, in Korean Laid-Open Patent No. 10-2012-0122943, the weights of film-forming resin and radical polymerizable resin are adjusted, and in Korean Laid-Open Patent No. In No. 10-2011-0063586, the thickness of the layer is adjusted, thereby reducing the flow of the composition. However, no ultra-low fluidity anisotropic conductive film for adjusting the content of insulating particles is disclosed.

Abstract

The present invention relates to an anisotropic conductive film that can prevent a short circuit by adjusting density of conductive particles pressed to electrode parts between electrodes and density of conductive particles in a space between the electrodes and exhibit enhanced cost-reduction effects and connection characteristics, and a semiconductor device connected thereby.

Description

Technical field [0001] The present invention relates to an anisotropic conductive film and a semiconductor device using the same. Background technique [0002] Anisotropic conductive film (ACF) is usually made by dispersing conductive particles such as nickel (Ni) or gold (Au) or conductive particles such as polymer particles of the above metal on a resin such as epoxy resin The film-shaped adhesive film means a polymer film having electrical anisotropy and adhesiveness that has conductivity in the film thickness direction of the film and insulation in the surface direction. [0003] After arranging this anisotropic conductive film between circuits and performing a thermocompression bonding process under specified conditions, the circuit electrodes are electrically connected by conductive particles, and a space is formed between the electrodes and the electrodes. It is filled with insulating adhesive resin and the conductive particles are independent of each other, thus having hig...
