Claim One:
1. A processing method for semiconductor dice on a wafer comprising: inspecting said semiconductor dice on said wafer for determining defects thereon and classifying each of said defects by size and location, said inspecting and classifying comprising classifying said each of said defects into one of size range populations of defects; assigning a weight to said each of said defects representing an estimated effect of said each of said defects on die yield for said semiconductor dice; determining an estimated die yield loss (DYL) for each die of said semiconductor dice based on number and weight of said defect(s) on each said die, summing all DYL of said semiconductor dice on said wafer to obtain a wafer yield loss (WYL); subdividing the defects into a plurality of size range populations of defects for said semiconductor dice; and determining a relative contribution of each size range population of defects of said plurality for said semiconductor dice to wafer yield loss WYL.
