Abstract:
1. A method for producing a defect card for semiconductor dies located on a semiconductive wafer, in which defective individual semiconductive dies are identified using a measuring procedure, the method comprising: producing first and second defect cards such that the defective individual dies are disjunctively associated with the first and the second defect cards, where the defective individual dies whose adjoining individual dies form an environment having a defect density up to a first value (δ producing a third defect card by classifying additional individual dies on the second defect card as defective, where adjoining individual dies of the additional defective individual dies form an environment having at least one defect density of a second value (δ producing a fourth defect card by unifying the third defect card with the first defect card.
