    摘要: In a method of classifying directional defects on an object straight lines are drawn from any defect among all defects on the object toward adjacent defects. At least three defects that are positioned within an allowable angle from the straight lines are classified as directional defects. Thus, only the directional defects among all the defects on the semiconductor substrate may be accurately classified after performing a chemical mechanical polishing (CMP) process, so that the CMP process may be effectively managed.
