|Abstract:||Negative Bias Temperature Instability (NBTI) is studied in plasma (PNO) and thermal (TNO) Si-oxynitride devices having varying EOT. Threshold voltage shift (Delta V(T)) and its field (E(OX)), temperature (T) and time (t) dependencies obtained from no-delay on-the-fly linear drain current (I(DLIN)) measurements are carefully compared to that obtained from Charge Pumping (CP). It is shown that thin and thick PNO and thin TNO devices show very similar NBTI behavior, which can primarily be attributed to generation of interface traps (Delta N(IT)). Thicker TNO devices show different NBTI behavior, and can be attributed to additional contribution from hole trapping (Delta N(h)) in pre-existing bulk traps. A physics based model is developed to explain the experimental results.|
