Abstract:
1. A method of forming a metallic wiring layer in a selected region of a substrate, comprising: a first process of introducing a gas of an organometallic molecule into a reaction chamber where a layer-stacked plate is arranged therein and forming an adsorbed molecular layer including the organometallic molecule on the layer-stacked plate; a second process of reducing a concentration of the gas of the organometallic molecule in the reaction chamber after forming the adsorbed molecular layer; a third process of light irradiating the selected region of the layer-stacked plate; a fourth process of removing from the layer-stacked plate the adsorbed molecular layer formed in a region other than the selected region of the layer-stacked plate; and a fifth process of forming a metallic film in the selected region of the layer-stacked plate.
