The way in which dies are allocated within a wafer is the subject of this paper. Standard ways of doing it are based on a software program, mainly in-house built, that uses default values for all the variables and do not take into account, in a direct mode, the actual distribution of yield versus distance to wafer edge in the manufacturing line where the chip is to be manufactured. We present a novel Software System for die allocation in the wafer, that uses an empirically obtained Yield Distribution Function (which gives the normalized yield for every X Y coordinate over the entire wafer area). The software developed gives as output the optimum die allocation in terms of yield.
