Claim One:
1. A method for evaluating the quality of a directed self-assembling method used for generating directed self-assembling patterns, the method comprising: obtaining at least one set of parameter values for a parameterized set of processing steps and material properties characterizing the directed self-assembling method, thus characterizing a specific directed self-assembling method used for generating a directed self-assembled layer; obtaining, using a scatterometer, a scattered radiation pattern on the directed self-assembled layer, wherein the directed self-assembled layer is obtained by applying the directed self-assembling method characterized by the set of parameter values on a guiding pattern comprising a number of induced, intended defects, thus obtaining scattered radiation pattern results for the directed self-assembled pattern; and determining, using a computing device and based on the scattered radiation pattern results, a qualification score identifying a robustness of the directed self-assembling method to the induced, intended defects in the guiding pattern and correlating the qualification score with the set of parameter values.
