发明名称 Method for fault analysis in wafer production
摘要 With the aid of the method for fault analysis according to the invention, a wide variety of chips are mapped by means of a transformation onto at least one uniform comparable wafer map. This transformation or resealing enables a chip-area-independent assessment of the products or the fabrication processes. The method for fault analysis according to the invention furthermore has the advantage that the information thus obtained can be stored very compactly in corresponding wafer databases and is thus available for further evaluations.
