Embodiment 1

[0032] Example 1: Preparation of anisotropic conductive film

[0033]Based on the parts by weight of the solid content of the following components, 10 parts by weight of butadiene resin, 30 parts by weight of acrylate-modified urethane resin, and 20 parts by weight of acrylic copolymer were mixed, melted and dispersed with a planetary mixer , 36 parts by weight of free radical polymer material, 2 parts by weight of organic peroxide and 2 parts by weight of conductive particles. Then, the mixture was applied to a release-treated 250 μm thick silicone polymer film (storage modulus: 668 kgf / cm 2 ), and dried in a hot air circulation at 60° C. for 5 minutes to dry the solvent, thereby preparing the anisotropic conductive film of Example 1.

Abstract

An anisotropic conductive film, a method for preparing a semiconductor device, and a semiconductor device, the anisotropic conductive film including a base film, the base film having a storage modulus of 5,000 kgf / cm2 or less or a coefficient of thermal expansion of 50 ppm / DEG C. or less at 100 DEG C to 150 DEG C; and an adhesive layer on the base film, the adhesive layer containing conductive particles.

Description

technical field [0001] The present invention relates to an anisotropic conductive film, its production method, a semiconductor device connected by it, and its production method. Background technique [0002] With the recent trend toward large and thin displays, the pitch between electrodes and lines has become finer. Anisotropic Conductive Film (ACF) plays a very important role as a terminal for connecting delicate circuits. [0003] Methods for Printed Circuit Board (PCB) / Outer Wire Bonding (OLB) and Chip-on-Glass (COG) / Film-on-Glass (FOG) applied to LCD and OLED module processing are divided into those in which ACF is cut into fixed lengths and mounted Pre-press process and main press in which COF, FPC and driver IC are fixed. Due to the pre-pressing process during installation, the failure rate is particularly high, and the main causes of failure include lack of margin for temperature and pressure. Examples of major failures include bubble generation due to wetting fai...
