Abstract

$BF_3$ gas has been used for semiconductor manufacturing process and applied in plasma etching, chemical vapor deposition, chamber cleaning processes etc,. $BF_3$ provides Boron and acts as a p-type doping in electrode in semiconductor. In this study, we investigate thermaldecomposition of alkali-boron complexes and suggest a simple way to produce $BF_3$ from $NaBF_4$ and $KBF_4$.

반도체용 특수가스인 BF3는 반도체 생산공정에서 웨이퍼의 플라즈마 식각 공정과 화학증기증착(CVD : Chemical vapor deposition) chamber 세정공정 등에 사용되며, $BF_3$ 가스는 boron Ion Implant 공정에서 p-type doping을 위한 원료 등으로 사용된다. 본 연구에서는 간단한 공정으로 $NaBF_4$$KBF_4$의 열분해를 통하여 $BF_3$ 가스의 생산에 대해서 연구 하였다.
