A new technique for I(DDQ) testing in nanometer technologies
I(DDQ) testing has become a widely accepted defect detection technique in CMOS ICs. However, its effectiveness in very deep submicron technologies is threatened by the increased transistor leakage current. In this paper, we propose a technique for the elimination, during testing, of the normal leakage current from the sensing node of a circuit under test. In this way the already known in the open literature I(DDQ) sensing techniques can be applied in the nanometer technologies. (C) 2002 Elsevier Science B.V. All rights reserved.
