  • Liquid-based masking layer
    Patent number: 10131570
    Abstract: A method of fabricating a liquid-based masking layer for a wet etching process, is disclosed. The method comprises forming a coated solid substrate by coating a solid substrate with a coating; forming a preliminary masking layer by removing parts of the coating which are not included in a pattern; depositing a porous surface on the preliminary mask to obtain a porous preliminary mask; forming a liquid-based masking layer by filling the pores of the porous preliminary mask with a filling liquid; and applying an etchant to a surface of the solid substrate and the liquid-based masking layer, etching parts of the substrate that are not covered with the liquid-based masking layer.
