Abstract
A hydrophobic surface coating, preferably obtained by chemical vapor deposition, comprises at least an upper thin layer formed by a compound selected from the group consisting of SiCO:H with x comprised between 1.4 and 2 and y comprised between 0.8 and 1.4 and SiCN:H with x' comprised between 1.2 and 1.4 and y′ comprised between 0.6 and 0.8, so as to obtain a free surface with a low wetting hysteresis. Such a hydrophobic surface coating can be arranged on the free surface of a microcomponent comprising at least one substrate provided with, an electrode array and particularly suitable for moving drops of liquid by electrowetting on dielectric.
