First Claim
Patent Images
1. A method for improving a yield of a product, the method comprising:
- selecting a set of golden tools from a set of manufacturing tools by using manufacturing data collected from a working piece processed using a plurality of recipes performed by each tool from the set of manufacturing tools to provide a ranking of tool performance for each tool in order to select the set of golden tools; and
providing a fully automated operational environment to produce a product using the set of golden tools,wherein selecting the set of golden tools further comprises;
selecting the plurality of recipes for each of the set of manufacturing tools;
excluding a recipe having excursion data from the plurality of recipes to form a subset of recipes;
benchmarking particles of the subset of recipes; and
benchmarking thickness capability index of the subset of recipes, wherein the benchmarking thickness capability index of each recipe relates to the degree each recipe meets a specified thickness.
