ABSTRACT:
A method of establishing a lot grading system for lots in a semiconductor manufacturing process includes defining a new lot grade for at least one lot in the semiconductor manufacturing process. The at least one lot is has a current lot grade and the new lot grade is dependent upon the current lot grade. The new lot grade is saved in a grading referenced database and the at least one lot in the semiconductor manufacturing process is updated with the new lot grade.
