Process for forming organic layers, organic electronic devices,and transistors

Abstract

Organic electronic devices are fabricated by a process includes forming an organic layer including: placing a first liquid composition over a first portion of a surface of a substrate without a well structure connected to or adjacent the first portion of the surface of the substrate, i) the first portion of the surface of the substrate has a first surface energy, ii) the first liquid composition includes a first liquid medium and iii) the first liquid composition has a second surface energy that is higher than the first surface energy; and evaporating the first liquid medium while the first liquid composition overlies the first portion of the surface of the substrate.

1 . A process of forming an organic layer comprising:
