Abstract

Analysis of IC technology trends indicates that Iddq testingmay be approaching its limits of applicability. The new conceptof the current signature may expand this limit underthe condition that an appropriate current-signature-basedtest methodology is developed. This paper is a first steptoward such a goal. It is focused on current signature stepdetection in a noisy test environment. Application of currentsignatures in die selection and defect diagnosis is discussedas well.
