Time dependent dielectric breakdown and stress induced leakage current characteristics of 8Å EOT HfO2 N-MOSFETS [PDF]
, 2010 In this work we present the time dependent dielectric breakdown (TDDB) characteristics of LaO capped HfO2 layers with an equivalent oxide thickness of 8Å. The layers show maximum operating voltages in excess of 1V. Such high reliability can be attributed

Pulsed voltage stress on thin oxides
Electronics Letters, 2000 Stress-induced leakage current (SILC) is one of the major problems found in ultra-thin oxides before the onset of soft or catastrophic breakdown during accelerated life tests. Quite often SILC is measured after constant current (CCS) or constant voltage (CVS) stresses, even though during the device life the operating conditions usually involve ...
