PROBLEM TO BE SOLVED: To take countermeasures to light malfunction in junction of a semiconductor chip to a substrate. SOLUTION: A junction material is transferred to an IC mounting region 6 on a transparent substrate 7 of a liquid crystal display device, and a liquid crystal driving IC 3 is positioned and mounted on the transparent substrate 7. In positioning, the junction material is before color development and is in a light transmitting state. Compression is carried out by a compression head 12 from an upper surface part of the mounted liquid crystal driving IC 3. A junction material 5b held by the IC mounting region 6 between the liquid crystal driving IC 3 and the transparent substrate 7 reacts and becomes hardened through heating and pressurization in compression. In the process, the junction material 5b develops color and has an effect of light screening. COPYRIGHT: (C)2004,JPO
