[0206] The acrylic rubbers shown in Table 2, the urethane acrylates described above, the phenoxy resins described above, and bis(2-methacrylic acid) as phosphoric acid esters were blended at the respective solid content mass ratios in the ratios shown in Table 2. Acyloxyethyl) acid phosphate (manufactured by Kyeisha Chemical Co., Ltd., trade name P-2M), tert-hexyl peroxy-2-ethylhexanoate (manufactured by NOF Corporation, trade name) as a radical polymerization initiator Named Percure HO (パ一キ Youa HO)), an adhesive composition containing liquid was prepared. Then, 3 volume % of electroconductive particles were dispersed in this adhesive composition containing liquid based on the total volume of solid content in an adhesive composition, and the circuit connection material containing liquid was prepared.

[0207] This circuit-connecting material-containing solution was left to stand in an environment of 25° C. and 60% RH for 1 hour, and then coated with a coating apparatus on one...

Abstract

The invention provides an adhesive composition, a circuit connection structure, a semiconductor device and a solar cell module. The adhesive composition comprises acrylic rubber, urethane acrylate and free radical polymerization initiators from 5-18 weight percentages of structural units of acrylonitrile.

Description

technical field [0001] The present invention relates to an adhesive composition, a circuit connection structure, a semiconductor device and a solar cell module. Background technique [0002] In a semiconductor element, a liquid crystal display element, etc., in order to join various members in an element, various adhesive compositions have been used conventionally. The properties required for the adhesive composition include adhesiveness as a representative and relate to many aspects such as heat resistance and reliability in a high-temperature and high-humidity state. [0003] In addition, the adherends used for bonding are represented by organic substrates such as printed wiring boards and polyimide, and metals such as copper and aluminum, or ITO, IZO, SiN, and SiO can be used. 2 and other substrates with various surface states. Therefore, the adhesive composition sometimes needs to be adapted to the molecular design of the adherend. [0004] Conventionally, as an adhes...
