Description
図9は、液滴の特徴部パターン内への浸透を達成するために、120度の接触角度という進んだ状態(advancement)(図8Bのθ2)を達成するのに必要な温度(Ttrans)のグラフ904を示す。図9は、160ミクロンのセル高さおよび62mN/mの液滴2面間張力を仮定する。これらの条件を用いて、図9は、セル内の流体の初期温度T0について、また、代表的な幅d(プロット901、902、および903で表され、図7Aおよび7Bにおいて寸法702として示される)について、それ以下では、液滴が特徴部パターンに浸透すると思われる所与の温度(Ttrans)が存在する。たとえば、セルの幅が、グラフ904のプロット902で示す15ミクロンであり、かつ、セル内の流体の初期温度T0が摂氏60度である場合、液滴が、プロット902上の点905で示す約摂氏15度の遷移温度Ttrans以下で特徴部パターンに浸透するようにさせるのに十分に、圧力が降下するであろう。
