1. A method for evaluating unit processes for a semiconductor manufacturing process, comprising: utilizing a combinatorial processing tool to perform a semiconductor manufacturing operation in a combinatorial manner wherein the semiconductor manufacturing operation is one of a wet chemical operation or a dry processing operation; utilizing the combinatorial processing tool to perform a first set of tests corresponding to input variables in order to evaluate material properties on a first substrate; inputting results of the first set of tests and the corresponding input variables into a computer-readable storage medium with an executable program stored thereon wherein the executable program includes a mathematical model to derive coefficients relating the corresponding input variables to the results of the first set of tests; utilizing the mathematical model to define new sets of varied input variables; utilizing the mathematical model to combine the new sets of varied input variables with the coefficients to derive a predicted output for each new set of varied input variables; utilizing the mathematical model to select a portion of the new sets of varied input variables; and utilizing the combinatorial processing tool to perform a second set of tests in a combinatorial manner according to the portion of new sets of varied input variables on a second substrate.
