Method of forming organic semiconductor device that includes forming electrode contact layer by treating electrode surfaces with substance containing substituted arene

A method of producing a semiconductor device, the method comprising:

• forming conducting electrodes over a substrate wherein the electrodes comprise metal;
• treating a surface of the electrodes with a treatment substance comprising an arene substituted with an electron-withdrawing group and a thiol group, the thiol group binding to the surface of the electrodes, thereby forming an electrode contact layer over the electrodes;
• and
• forming an organic semiconductor layer over the substrate and electrodes;
• wherein the substrate and electrodes are baked before the organic semiconductor layer is formed, so as to dehydrate the surface of the electrode contact layer and thereby promote crystal nucleation of the organic semiconductor on a surface of the electrode;
• wherein the bake is performed at a temperature greater than or equal to 60° C. and less than or equal to 140° C.
