Description
−腐蝕液は露出表面領域のみならず被覆材料も腐蝕する。暴露期間により被覆は薄くなるか完全に除去され、本来は保護されねばならない基板表面からの材料除去が続いて起こる。
−不完全エッチングが起こりうる、即ち、マスク(被覆)の下の側面に既にできている溝の側壁から当該被覆下の側面に沿って起こるので、被覆層下の末端が縁を持ち不明確な外観を有する。更に、出来上がった溝の壁は滑らかではない。
−基板上の単一溝内および/または数個の溝に亘る非均一エッチング速度が不明確な深さを生じる。
−エッチングで除去した材料の望ましくない再堆積。エッチングで除去した基板および/または被覆材料が望ましくない様式または当該基板の望ましくない部位および/またはエッチング装置に沈着しがちで、使用に適さない結果を招くかエッチング装置がもう操作できないようになる。
−深溝(深さT>200μm)を作る際に、当該エッチング速度が遅すぎて経済的に効率的な結果が得られないことがありうる。
