Control of cohesive-force ordering in organic-inorganic hybrid pillar arrays

説明
Organic-Inorganic hybrid pillar arrays have been controlled by cohesive force during drying in photolithography. Two-dimensional periodic pillars with micrometer repetitions were fabricated from an organic-inorganic hybrid material. The pillars were gathered at the top and gtop-gatheringh pillar patterns were obtained depending on pillar sizes such as height of the pillars and distance between neighboring pillars and types of rinse liquids. The top-gathering pillar patterns could be obtained easily in the pillar arrays with same structural parameters using 1-PrOH as a rinse liquid rather than water. From in situ observation of the drying rinse liquids, it was found that the drying of 1-PrOH differs from that of water in the pillar arrays because of the difference in the contact angles. Top-gathering pillars were partially introduced in a homogeneous periodic pillar array by the different pillar formations between two types of rinse liquids.
