摘要

A method for forming a contact hole includes forming a lyophobic area by applying a liquid droplet of a lyophobic material on a region for forming a contact hole on a wiring, the lyophobic material being lyophobic to a liquid that contains an insulating layer forming material; and forming an insulating layer by applying a droplet of the liquid containing the insulating layer forming material so as to cover the wiring except for the lyophobic area, wherein the contact hole formed penetrates through the insulating layer to be connected to the wiring covered by the insulating layer.
