Abstract (en)

[origin: WO2011067512A1] The invention relates to a method for structuring a surface, in other words, for forming at least one set of irregularities or patterns (2) having a submicronic height H and at least one characteristic lateral dimension W referred to as the micronic or submicronic width, on a surface of a material (1), in particular a glass, by means of reactive ion-beam etching, characterised in that said method includes the following steps: providing said material with a thickness of at least 100 nm, the material being hybrid and solid and including a single or mixed Si oxide, the molar percentage of oxide in the material being at least 40%, in particular 40% to 94%, and at least one species, separate from the Si of the oxide, in particular a metal, the molar percentage of species in the material ranging from 1% to 50% and being lower than the percentage of said oxide, at least the majority of the species having a largest characteristic dimension smaller than 50 nm, said hybrid material in particular being metastable prior to said etching; optionally heating said hybrid material prior to said etching; and structuring the surface of said hybrid material with an etching time of less than one hour on an etching surface of more than 1 cm2 until said set of patterns is formed, the structuring step optionally including heating the hybrid material.
