Abstract

A super hydrophobic surface is realized by forming double roughness on a silicon surface. A deep silicon etching and a gas phase isotropic silicon etching (XeF2) are used as the fabrication method for two different scales of roughness. Combination of these two techniques enables the uniform formation of double roughness on a silicon surface. The fabricated surface shows the tendency of preferring Cassie state [1] to Wenzel state [2] and a durable super hydrophobic property. Through a series of experiments, this study also offers a verification of the previous theoretical prediction [3] for the amplification of contact angle on a surface with double roughness.
