Description
「電子デバイスの一部区域から保護被覆を除去するための方法」という名称の米国仮特許出願第61/750,257号(「257号仮出願」)及び「電子デバイスを保護被覆の塗工に向けてマスクするための方法及びマスクされた電子デバイス」という名称の米国仮特許出願第61/750,254号(「254号仮出願」)の出願日である2013年1月8日に対する優先権の恩典を求める主張をこれによりなす。254号仮出願及び257号仮出願のそれぞれの開示全体をこれによりここに援用する。
集束型有向性プロセスの使用に代わるものとして、弱集束型、非集束型、及び/又は非有向性の除去技法(例えば、研磨材料を用いる非有向性アブレーション、幅広レーザービームの使用、プラズマエッチング、など)を、基板及びその上の保護被覆の上方に配置されたテンプレートと併用して、保護被覆の一部分をアブレーションによって除去するようにしてもよい。テンプレートは、保護被覆の除去したい1つ又はそれ以上の部分、例えば、最終的には保護被覆で覆われない状態にさせるつもりの構成要素又は機構の上に置かれている保護被覆の1つ又はそれ以上の部分を露出させる。テンプレートは、保護被覆によって覆われたままにしておくことを意図した構成要素又は機構を遮蔽する。その様な実施形態では、除去媒体が被覆させるつもりの構成要素又は機構から保護被覆を除去するのをテンプレートが防止するので、除去媒体は有向的に適用される必要がある。
表面が親水性であれば、水は若干広がり、表面との90°未満の水接触角を形成する。対照的に、疎水性の表面は、本開示上は耐水性又はより広範には耐湿性であると見なすことのできる表面であって、水が広がるのを防止し、その結果、水接触角度は90°以上となる。表面に水玉が多いほど、水接触角は大きい。水滴が表面で玉状になっていて、表面との水接触角が約120°以上であるとき、当該表面は高疎水性であると見なされる。水が表面に接触する角度が150°を超えているとき(即ち、表面の水滴がほぼ球状であるとき)、当該表面は「超疎水性」であると言える。
図2は、除去媒体160を保護被覆120へ非集束方式(例えば、非選択的、など)で適用するように構成されている除去部要素150の1つの実施形態を示している。除去媒体160が、基板100の特定の構成要素又は機構102を覆ってその場に残留させたい保護被覆120の部分を除去するのを防止するために、テンプレート220が非集束型除去プロセスと併用されてもよい。テンプレート220は、構成要素又は機構102(図2では、構成要素又は機構102c)を除去媒体160に露出させ、保護被覆120の残り部分(例えば、構成要素又は機構(図2では、構成要素又は機構102a及び102b)の上に横たわっている部分)を除去媒体160から遮蔽することになる。従って、テンプレート220は、1つ又はそれ以上の開口240の画定されている中実構造250を備えており、開口240を保護被覆120の所定部分を除去媒体160に露出させる位置に配し、同時に、中実構造がその場に留置させたい保護被覆120の部分を遮蔽して除去媒体160が保護被覆120のそれらの部分を除去するのを防止するようにしている。
