Method and system for combinatorial changes in the process sequence material, and unit process

摘要

A method for analyzing and optimizing fabrication techniques using variations of materials, unit processes, and process sequences is provided. In the method, a subset of a semiconductor manufacturing process sequence and build is analyzed for optimization. During the execution of the subset of the manufacturing process sequence, the materials, unit processes, and process sequence for creating a certain structure is varied. During the combinatorial processing, the materials, unit processes, or process sequence is varied between the discrete regions of a semiconductor substrate, wherein within each of the regions the process yields a substantially uniform or consistent result that is representative of a result of a commercial manufacturing operation. A tool for optimizing a process sequence is also provided.
