摘要
Current-voltage measurements indicated that RF hydrogen/deuterium remote plasma treatment of thin p-Si/SiO2/HfO2 structures proved to be detrimental in terms of dielectric reliability. By using capacitance-voltage measurements we demonstrate that this reported degradation was not attributed to plasma-induced defects but rather due to an enhanced liberation of hydrogen and deuterium species during the electrical stress.
