前記マスクを除去するステップと
を含む。

前記静止部分に対して前記移動部分を移動させるアクチュエータと、
前記移動部分と前記静止部分とを相互接続する機械シールであり、重合シロキサン類及びフッ化ポリオレフィン類を含むグループから選択されたポリマー材料を含む機械シールと
を備えたノズルアセンブリを提供する。
駆動回路に接続する第1の能動要素と、
第2の受動要素と
を備え、
第1の要素に電流が流されたときに第1の要素が第2の要素に対して膨張するように第2の受動要素が第1の要素と機械的に協力し、その結果、アクチュエータが曲がる
サーマルベンドアクチュエータである。
図1を参照すると、複数のノズルアセンブリを備えた印刷ヘッドの一部分が示されている。図2及び3は、これらのノズルアセンブリのうちの1つのノズルアセンブリの断面図及び破断透視図を示す。
上述のプロセスの代替プロセスとして、ノズル表面56は、ノズル開口のエッチング(すなわち図10及び11に示された段階)の直後にその上に付着させた疎水性ポリマーを有する。後にフォトレジストスカフォルド層を除去しなければならないため、このポリマー材料はアッシングプロセスに対して抵抗性を有するべきである。好ましくは、このポリマー材料が、O2又はH2アッシングプラズマによる除去に対して抵抗性を有するべきである。本発明の出願人は、疎水性であり、同時にO2又はH2アッシングに対して抵抗性を有するという上記の要件を満たすポリマー材料群を識別した。これらの材料は一般に重合シロキサン類(polymrized siloxanes)又はフッ化ポリオレフィン類(fluorinated polyolefins)である。より具体的には、ポリジメチルシロキサン(polydimethylsiloxane:PDMS)及び過フッ化ポリエチレン(perfluorinated polyethylene:PFPE)はともに特に有利であることが示されている。このような材料はO2プラズマ中で不活性化(passivating)表面酸化物を形成し、続いて、比較的に速くそれらの疎水性を回復する。これらの材料の他の利点は、二酸化シリコン、窒化シリコンなどのセラミックに対して優れた付着性を有することである。これらの材料の他の利点は、フォトパターニングが可能(photopatternable)なことであり、このことはこれらの材料を、MEMSプロセスにおいて使用するのに特に適したものにする。例えば、PDMSはUV光で硬化可能であり、このことにより、PDMSの未露光領域を比較的に容易に除去することができる。
代替プロセスとして、図7及び8によって示された段階の直後に疎水性ポリマー層100を付着させる。したがって、リムエッチングによってリム25が画定された後に、ただしノズルエッチングによってノズル開口26が画定される前に、ノズル表面に疎水性ポリマーがスピンコートされる。
図25及び26は、疎水性ポリマー100をノズル開口エッチングのエッチングマスクとしてどのように使用することができるかを示す。一般に、ポリマー100とルーフ21との間の異なるエッチング速度は、上で論じたとおり、十分なエッチング選択性を提供する。
印刷ヘッドのノズル表面を疎水化することができる方法について論じたが、類似の態様でいかなるタイプの印刷ヘッドを疎水化することもできるということが理解できるであろう。とは言うものの、本発明は、サーマルベンドアクチュエータノズルアセンブリを備える本発明の出願人の以前に記載された印刷ヘッドに関する特定の利点を実現する。したがって、次に、このような印刷ヘッドにおいて本発明をどのように使用することができるかについて論じる。
