Abstract

MOSFET subthreshold leakage currents are improved by their exposure to hydrogen radicals, generated in microwave-excited Ar-H2 plasma. This mixture was chosen since Ar plasma resulted in both high production of hydrogen radicals and at the same time, only small changes of the exposed MOS characteristics. Experiments including exposure to plasma with different total and partial pressures and inert gases are presented.
