Description
本発明の方法の実施態様が添付図面に概略的に図示してあり、添付図面の第1A〜1C図は微小流体素子構造体の製作での種々の工程を示しており、第2図は最終製品の横断面図である。
50μmの高さ、250μmの幅、約80mmの長さの閉鎖したまっすぐなチャンネルを持つポリマー構造体を以下の方法で製造した。
所望のチャンネル形状配置に対応する表面レリーフ構造体を有するシリコンモールドをそれ自体公知の方法で製作した。シリコンプレートの表面をまず約1100℃で酸化して8000オングストローム厚の酸化層を形成した。洗浄してからオーブン内で脱水し、ヘキサメチルシランで下塗りした後、フォトレジスト層を酸化層にスピンコートし、オーブン内でベークすることによって安定化した。
