16th International Conference on VLSI Design Immediate Neighbor Difference IDDQ Test (INDIT) for Outlier Identification New Delhi, India January 04-January 08 ISBN: 0-7695-1868-0
Increasing magnitude and variation in leakage current make it impossible to distinguish between faulty and fault-free chips using single threshold method. Neighboring chips on a wafer have similar fault-free properties. By obtaining differences in IDDQ values it is possible to discriminate faulty dice. In this paper we describe a methodology in which comparison of IDDQ of a die with that of its neighboring dice on the wafer is evaluated for screening faulty chips at the wafer level. The analysis based on the SEMATECH test data? is presented.
