Technical Examples

A thin hard mask is formed over a semiconductor substrate. The thin hard mask allows diffusion of a sacrificial material or pore-forming agent therethrough to form an underlying air gap or porous dielectric region. The thin hard mask may be a polymer or an initially porous material that may be later densified. The thin hard mask may be used to prevent etch steps used in forming an unlanded via from reaching layers below the hard mask.
