摘要:
A method of forming an opening in a disclosed ILD is described. The ILD in one embodiment includes a matrix material and a photosensitive porogen. Hard sidewalls are formed in the ILD allowing a thin barrier layer to be used in a dual damascene copper and porous low-k without pore sealing steps.
