$NH_3-O_2$의 열반응에 의해 산화막을 성장시키는 새로운 방법을 소개하고, 기존의 건식산화방법을 이용한 $SiO_2$박막의 특성을 비교 설명하였다. $NH_3$의 유량에 따라서 박막의 성장비가 증가하고, 성장된 막의 구성성분이 건식산화때와 같음을 확인하였다. C-V특성곡선에서도 $Q_{OX}$와 $Q_{SS}$가 거의같았고 히스테리시스현상도 없었다. 또한 n-MOS트랜지스터를 제작하고 측정한 결과 $I_D$-$V_{DS}$특성곡선이 건식산화와 비교하여 우수함을 확인했다.
A new method was developed for growing oxidation film by thermal reaction of $NH_3$ and $O_2$. The growth rate increased with the increase of partial pressure of $NH_3$. Optical transparency of the growth film was 12% at the wave number 1100 $cm^{-1}$ compared with 17% by thermal dry oxidation method, and the quality was much better. In C-V characteristic curve, $Q_{OX}$ was almost equal to $Q_{SS}$ and no hysteresis phenomena was observed. n-MOS transistors fabricated with this new method showed $I_D$-$V_{DS}$ characteristics better than thermal dry oxidation method.
