摘要:
A low k dielectric layer is formed by depositing an unset dielectric layer on a substrate, the dielectric layer including Silicon, Carbon and Oxygen. The surface of the dielectric layer exposed to an activated gas to form a semi-permeable skin on or of the surface of the layer. The layer is then cured to render at least part of the layer porous.
