Abstract:
A computer readable memory for storing a diagnosis program for diagnosing a manufacturing process of a semiconductor device composed of a plurality of logic circuit blocks by controlling a semiconductor device manufacturing process diagnosis device, the diagnosis program comprising the steps of:physical abnormality position detection step of detecting a physically abnormal part of a semiconductor device to be diagnosed;electrical characteristics measurement step of measuring electrical characteristics of said semiconductor device;block extraction step of extracting a block of circuits constituting said semiconductor device contained in a predetermined region covering a physically abnormal part detected at said physical abnormality position detection step;abnormal block discrimination step of determining whether said block extracted at said block extraction step and an abnormal block causing abnormality of electrical characteristics of said semiconductor device coincide with each other based on electrical characteristics measured at said electrical characteristics measurement step;abnormality position detection step of detecting a position causing said abnormality of electrical characteristics within a block determined to be an abnormal block at said abnormal block discrimination step; andfailure determination step of determining, depending on whether said position detected at said abnormality position detection step substantially coincides with a physically abnormal part detected at said physically abnormal part detection step, whether abnormality of electrical characteristics caused at said position derives from said physical abnormality.
