Abstract:
Example embodiments relate to selective deposition of metal-organic frameworks. One embodiment includes a method of forming a low-k dielectric film selectively on exposed dielectric locations in a substrate. The method includes selectively depositing a metal-containing film, using an area-selective deposition process, on the exposed dielectric locations using one or more deposition cycles. The method also includes providing, at least once, a vapor of at least one organic ligand to the deposited metal-containing film resulting in a gas-phase chemical reaction thereby obtaining a metal-organic framework which is the low-k dielectric film. The low-k dielectric film has gaps on locations where no metal-containing film was deposited.
