The invention relates to materials and methods of forming controlled voids in dielectric layers. One technical proposal of the invention is a method of forming an air gap on a substrate. The method includes providing a substrate; depositing a sacrificial material on a substrate by depositing at least one precursor of the sacrificial material; depositing a composite layer, containing a porogen material, over the sacrificial material; removing of the porogen material from the composite layer to form a porous layer; and removing the sacrificial material to provide the air gap. The sacrificial material precursor is selected from an organic porogen, silicon, and a polar solvent soluble metal oxide, and is removed by, as appropriate, applying energy or contacting the layered substrate with a removal medial, such as a fluorine containing reagent or polar solvent, which diffuses through the porous layer.
