図1は、第1実施形態に係る塗布装置を例示する模式側面図である。図2は、第1実施形態に係る塗布装置を例示する模式的上面図である。
図1および図2に例示した塗布装置は、メニスカス法によって、一次的な特膜を形成するものであるが、一次的な塗布膜の均一性を改善するために、ノズル106の位置を調整するノズル位置調整部材110や、塗布バー101とノズル106の距離を検出するノズル位置検出部材111などをさらに具備することができる。
また、均一化バー105と基材107の間隔を制御する部材を具備することが好ましい。このためにはギャップリングやマイクロメーター等を使用することができる。
第2実施形態は、塗布方法に係る。実施形態に係る塗布方法においては、例えば、第1実施形態に関して説明した塗布装置10(およびその変形)を用いて塗布が行われる。
実施形態において、基材107が垂直方向に搬送される位置で、塗布液103が基材107に塗布されても良い。これにより、例えば、重力の効果がメニスカスに加わり、高速でも均一な膜が得やすくなる。
