Method of Preparing and Using Photosensitive Material

摘要

Provided in one embodiment is a method that includes selecting a photoresist that is one of a positive-tone photoresist and a negative-tone photoresist. A first additive or a second additive is selected based on the photoresist. The first additive has a fluorine component and a base component attached to a polymer and is selected if the a positive-tone resist is provided. The second additive has the fluorine component and an acid component attached to the polymer and is selected with a negative-tone resist is provided. The selected photoresist and the selected additive material are applied to a target substrate.
