Description
直径300mmのシリコンウエーハ上に形成されたアルミニウム膜を(1)従来使用されている代表的な有機フッ素系薬液(有機溶媒にフッ化アンモニウムを溶解したもの)で10分間処理した後、(2)約0.05重量%に希釈したフッ酸で20秒間処理した後、(3)約0.05重量%のフッ酸で20秒処理した後、約0.1重量%のコリン水溶液で5秒間処理(HF→コリン)した後に、それぞれアルミニウム膜表面に残留しているフッ素濃度を純水で抽出し、イオンクロマトグラフィーで分析した。結果を図4に示す。なお、各薬液の処理時間はアルミニウムをRIEにより加工した後の加工残留物が除去できる時間により決定した。
図3に関して説明したとおりに絶縁層24(酸化シリコン層)にコンタクトホール241を形成した後、アルミニウム膜23の表面を、実施例1で記載したとおりの有機フッ素系薬液よる処理と、HF→コリン処理とを行った後、5日放置したときのアルミニウム膜23の表面状態を光学顕微鏡にて観察し、その顕微鏡写真をトレースした(図5)。図5(A)は、有機フッ素系薬液で処理した場合を示すものであるが、アルミニウム表面がコロージョンを起こしているのが観察された(閉鎖曲線で示す)。これに対し図5(B)は、HF→コリン処理を行った場合を示すものであるが、アルミニウムのコロージョンが抑制されており、非常に良好な表面を保っていることが観察された。これは、実施例1の結果から、アルミニウム表面に残留したフッ素が多いと放置によるアルミニウムコロージョンを誘発しやすいためと予想されるが、HF→コリン処理を行って残留フッ素量を低減した条件ではアルミニウムコロージョンが抑制できたことによる。
