Current Signatures: Application

Analysis of IC technology trends indicates that Iddq testing may be approaching its limits of applicability. The new concept of the current signature may expand this limit under the condition that an appropriate current-signature-based test methodology is developed. This paper is a first step toward such a goal. It is focused on current signature step detection in a noisy test environment. Application of current signatures in die selection and defect diagnosis is discussed as well.
