Abstract

We investigated the growth of a SiNxCy dielectric sealing layer on a porous low dielectric constant (low-k) substrate using plasma-enhanced atomic layer deposition (PE-ALD). A porous low-k substrate was repeatedly exposed to bis(dimethylamino)dimethylsilane (BDMADMS) and a hydrogen plasma. A SiNxCy sealing layer grown by PE-ALD was formed without any penetration of the pores within the porous low dielectric substrate. Our technique provides for the deposition of a dielectric sealing layer that prevents pore penetration of a low-k material.
