Abstract :
Temperature dependencies of several kinds of leakage current in MOSFETs were precisely investigated. We proposed the new concept of low-temperature standby-current (LTSC) screening for discriminating highly reliable CMOS LSIs based on the different temperature dependence between the normal and abnormal leakage current. This technique has a sufficient threshold current margin for the pass/fail decision making and is effective for screening deep-submicron CMOS LSIs with low threshold voltage MOSFETs
