Semiconductor device mounting method, semiconductor device mounting structure, electro optical device, electro-optical device manufacturing method and electronic device

摘要

The invention seeks to provide a new semiconductor device mounting method, a semiconductor device mounting structure, an electro-optical device and an electronic device that can improve the reliability of conductively joined portions, even if the numbers of wiring terminals and electrodes increases and intervals therebetween are narrowed. A wiring terminal is formed on a wiring substrate, and an electrode is formed on a semiconductor device. Here, the width of the wiring terminal is formed so that it becomes smaller than the width of the electrode. When the semiconductor device is mounted on the wiring substrate, the wiring terminal becomes embedded in the electrode due to applied pressure. It is preferable for the embedding amount of the wiring terminal to be within the range of about 1 µm to 5 µm.
