Description
インクジェットのプリントバー及び他の流体微小電子機械システム(MEMS)の構成要素は、マイクロ流体デバイスを含むことが多い。係るマイクロ流体デバイスは一般に、セラミック材料、又は多層金属および/またはセラミック材料から形成される。マイクロ流体デバイスの形成方法は、以下に限定されないが、正確な位置合わせと平面性でダイをデバイスに取り付けること、スロット間での色混合なしに数桁にわたる流体相互接続を達成すること、電気相互接続を達成すること、インク又は他の流体の腐食に耐えるデバイスを形成すること、及びそのようなデバイスを経済的に形成することを含む基本的な問題に対処することを目的とする。
本明細書で開示されたマイクロ流体デバイスの実施形態は、有利にはガラスから形成される。ガラスのデバイスは一般に、各基板に画定された流体機構が実質的に位置が合う(align:整列する)ように互いに結合された複数の基板を含む。流体機構、流体機構の入口、及び/又は流体機構の出口は、サイズ及び/又は形状が異なってもよい。マルチ基板デバイスは、扇状に広がる流体構造または三次元相互接続を有するように構成されてもよい。ガラス基板は、有利には基板表面と同一平面で取り付けられた電子回路、ダイ、又は他のデバイスを格納するためのポケットを有するように構成されることができ、それにより電気相互接続が比較的柔軟で頑強で単純になる。更に、ガラス基板は、シリコンと適合する熱膨張率を有する。このことは、製造中(例えば、ボンディングプロセス)及びその後の使用中(例えば、サーマルインクジェット印刷)にデバイス性能を強化すると考えられる。
