Abstract
Description
図2Aは、この例ではアルマイト表面を有する部品204の概略断面図である。表面が予め洗浄されて(ステップ104)、有機堆積物もしくは無機堆積物またはマイクロコンタミネーションが除去されることで、化学前駆体剤による次の反応のために表面終端基を化学的に活性化させる(例えば、ヒドロキシル化する)。少なくとも1つの活性表面は、部品204の上に存在し、皮膜付着抑制が必要になるだろう領域のみを露出するマスキング法を用いてマスキングされる(ステップ108)。マスキング法は、ハードマスクまたはソフトマスクを用いて実行されうる。マスキング法で用いられる材料のいくつかの例は、皮膜塗布で用いられるもの(カプトン、粉体塗装、3Mテープ、感光性レジスト、塗料、シリコン、ハードマスクなど)などの粘着テープを含みうる。図2Bは、カプトンマスク208が施された後の部品204の概略断面図である。
他の例では、気相堆積されうる、プラズマ溶射皮膜プロセスと互換性のある無機材料から、薄膜マスクなどの犠牲層が作られる。プラズマ溶射皮膜プロセスが完了した後に、犠牲層は次に、湿式洗浄、および/または、ウェットエッチングされて、溶射皮膜と比べて良い犠牲層のエッチング選択比で過剰噴霧皮膜を切り取り剥離しうる。
