WIRING BOARD, SEMICONDUCTOR DEVICE, AND THEIR MANUFACTURING METHODS

摘要

PROBLEM TO BE SOLVED: To provide a technique by which fine wiring can be formed in forming a pattern of wiring etc., by discharging droplets. SOLUTION: In forming a pattern by the droplet discharging method (also called as the ink-jet method), a coating film of a porous material (including a poromeric material) is formed as the base of the pattern. A wiring board has a porous film and a conductive layer formed on the porous film. A semiconductor device has a thin film transistor using the above-mentioned conductive layer as a gate electrode.
