Abstract
We developed a practical large-radius neutral beam enhanced CVD with a dimethoxy tetramethy ldisiloxane (DMOTMDS) to form low-k SiOCH film on 8-inch Si wafers. We fabricated extremely non-porous film with an ultra-low k-value of 2.3 and a sufficient modulus (>10 GPa). This particular film did not show any damage from the oxygen plasma and acid or alkali solutions used in the fabrication process. Furthermore, the dense film almost completely resisted Cu diffusion into the film during thermal annealing.
