Abstract:
A method of analyzing semiconductor production data from a production line, comprising the steps of:establishing a table namespace of old semiconductor cluster classifications having first attributes;selecting from a list box a new semiconductor cluster classification having second attributes;adding said selected new cluster classification to said table namespace;choosing said new semiconductor cluster classification from said table namespace;executing an analytical routine on said production data from said new semiconductor cluster classification with said second attributes;choosing a plurality of filters associated with said old and new semiconductor cluster classifications;applying said plurality of filters to said semiconductor production data in sequence;removing non-defect semiconductor product data from said semiconductor production data;color coding each of said semiconductor cluster classifications so that said classifications can be more easily distinguished; andif results of the executed analytical routine exceed a predetermined control level, sending a command to the production line to initiate a process change.
