The onium salt can be used for a chemically amplified resist composition. The resist composition exhibits a high sensitivity, high resolution, having improved lithography properties such as LWR of line patterns, CDU of hole patterns, exposure latitude (EL), and depth of focus (DOF), and capable of suppressing collapse of resist patterns in photolithography using high-energy radiation such as a far ultraviolet ray, EUV, or an electron beam (EB) independent of whether it is of positive or negative tone, and to provide a pattern forming process. The onium salt having the formula (1).

A conductive ink, a preparation method and application thereof are provided and relate to the field of conductive ink technology. The conductive ink includes the following components in weight percentage, based on a total weight of the conductive ink being 100%: 1% to 85% of an organic conductive material, and 15% to 99% of a solvent. The solvent has a boiling point lower than or equal to 150 C. The conductive ink provided in the present application includes the organic conductive material and the solvent. Since the solvent having a boiling point lower than or equal to 150 C., the conductive ink of the present application not only dries quickly during coating and has high production efficiency, but also forms a transparent conductive film layer that is uniform, flat, and dense, and has good product quality.
