PATTERN FORMING METHOD, ELECTRONIC WIRING SUBSTRATE, OPTICAL DEVICE, AND PATTERN FORMING DEVICE

摘要

A pattern forming method ejects droplets of ink onto a base material by an inkjet method. A base material (Z) has a first region (42) and a second region (44) that differ in surface energy. At least two types of ink, a first ink (52a) that has volatile characteristics and a second ink (54a) that has curing characteristics, are used in the ink. The first ink (52a) and the first region (42) are lyophilic, and the second ink (54a) and the second region (44) are lyophilic. The pattern forming method has a droplet ejection step in which the first ink (52a) is ejected to the first region (42) and the second ink (54a) to the second region (44) simultaneously by a multipass system.
