초록

The NH$_3$oxidation, which forms thermal oxide layer on silicon substrate with pure $O_2$gas added with small amounts of NH$_3$gas, has good interface sates due to activated gettering effect during oxidation. The superiority of interfae state in NH$_3$ oxidation method is not affected by preprocess but by gettering during oxidation. The dramatec reduction fo interface state is conformed with observing OSF when NH$_3$ oxide is annealed in NH$_3$ atmosphere.
