BASIC MATERIAL FOR PATTERNING AND PATTERNING METHOD

摘要

A patterning method in which a liquid drop is applied across a water repellent region and a hydrophilic line to satisfy the expression (1) when the water repellent region where the liquid drop has a first contact angle at the time of touching an objective plane before being ejected onto a substrate, and the hydrophilic line adjacent to the water repellent region and becoming a pattern to be formed where the liquid drop has a second contact angle smaller than the first contact angle are formed on the substrate. D<= Lx{1+2(cosTheta2- cosTheta1)}...(1) where, D: diameter of liquid drop, L: width of pattern, Theta1 : first contact angle, Theta2: second contact angle. Since the number of liquid drops being ejected is decreased, an increase in tact time and a decrease in ink jet lifetime can be prevented.
