发明名称 Method of determining optimum optical conditions for an anti-reflective layer used in a method of forming a resist pattern.
摘要 A method of determining an optimum condition of an anti-reflective layer upon forming a resist pattern by exposure with a monochromatic light, a method of forming the anti-reflective layer therewith, a method of forming a resist pattern using a novel anti-reflective layer obtained therewith, and a method of forming a film. The optimum condition of the anti-reflective layer is determined and the anti-reflective layer is formed by the methods described below. Further, an optimal anti-reflective layer is obtained by the method which is used for forming the resist pattern. The method comprises (I) forming an equi-contour line for the amount of absorbed light regarding a photoresist of an optional film thickness using the optical condition of the anti-reflective layer as a parameter, (II) conducting the same procedure as in (I) above for a plurality of resist film thicknesses, (III) finding a common region for the amount of absorbed light with respect to each of the traces obtained, thereby determining the optical condition for the anti-reflective layer, (IV) applying same procedures as described above while changing the condition of the anti-reflective layer, thereby determining the optical condition for the anti-reflective layer, and (V) determining the optimum optical condition such as the kind and the thickness of the anti-reflective layer under a certain condition of the anti-reflective layer. <IMAGE>
