Description
フッ酸と塩酸等の非酸化性の酸との混合水溶液の場合、フッ酸は弱酸でありフッ酸溶液のpHは2〜3程度であるが、塩酸等の非酸化性の酸を添加することで混合水溶液のpHがより低下し、pHが低いほどTiO2中のイオン化するTiの存在比率が高くなる。そのため、フッ酸とTiO2との反応により安定的にTiイオンが生成し、TiO2のエッチングレートが向上するものと考えられる。
一方、フッ酸と有機酸との混合水溶液の場合、フッ酸単独の水溶液よりもフッ酸の電離度が低下する。すなわち、有機酸を混合することにより水溶液中の[HF]濃度が上昇する。したがって、フッ酸と有機酸との混合水溶液によりTiO2のエッチングレートが上昇するのは、TiO2のエッチングは未解離のHFにより進行するためと考えられる。
本発明はこのような知見に基づいてなされたものである。
図1は、本発明の一実施形態に係る酸化チタン膜の除去方法を実施するための酸化チタン膜の除去装置を示す断面図である。
フッ酸(HF)と非酸化性の酸との混合水溶液の場合、フッ酸は弱酸でありフッ酸溶液のpHは2〜3程度であるが、塩酸等の非酸化性の酸を添加することで混合水溶液のpHがより低下する。図2はTiのpH−酸化還元電位図である。H2Oの存在下では、図2の2本の斜め破線の間の領域をとる。図2に示すように、pHが低くなるほどイオン化したTi(TiO++)の存在比率が高くなり、pH<0になるとほぼ全部がTiO++となる。つまり、pHが低いほど安定的にイオン化することを示している。したがって、フッ酸に非酸化性の酸を添加してpHを低下させた混合溶液は、フッ酸とTiO2との反応により安定的にTiイオンが生成し、TiO2のエッチングレートが向上するものと考えられる。このときpH<0であることが好ましい。また、非酸化性の酸の場合は、酸化性の酸である硝酸と異なり、フッ酸との混合水溶液はシリコンをほとんどエッチングしない。
