Claim One:
1. A method for tuning process parameters of a process tool such that the wafers processed by the process tool exhibit desired process monitor items, the method comprising: defining behavior constraint criteria and sensitivity adjustment criteria; generating a set of possible tool tuning process parameter combinations using process monitor item data associated with wafers processed by the process tool, sensitivity data associated with a sensitivity of the process monitor items to each process parameter, the behavior constraint criteria, and the sensitivity adjustment criteria, wherein the generating the set of possible tool tuning process parameter combinations includes: applying a discount of the sensitivity adjustment criteria to a set of process parameter values for each process parameter to generate a discounted set of process parameter values for each process parameter, wherein the discounted set of process parameter values has a reduced number of process parameter values; and generating the set of possible tool tuning process parameter combinations using the discounted set of process parameter values; generating a set of optimal tool tuning process parameter combinations from the set of possible tool tuning process parameter combinations; and configuring the process tool according to one of the optimal tool tuning process parameter combinations.
