摘要:
Embodiments of the invention provide a method for forming tantalum nitride materials on a substrate by employing an atomic layer deposition (ALD) process. The method includes heating a tantalum precursor within an ampoule to a predetermined temperature to form a tantalum precursor gas and sequentially exposing a substrate to the tantalum precursor gas and a nitrogen precursor to form a tantalum nitride material. Thereafter, a nucleation layer and a bulk layer may be deposited on the substrate. In one example, a radical nitrogen compound may be formed from the nitrogen precursor during a plasma-enhanced ALD process. A nitrogen precursor may include nitrogen or ammonia. In another example, a metal-organic tantalum precursor may be used during the deposition process.

An apparatus for generating gas for a processing system is provided. In one embodiment, an apparatus for generating gas for a processing system includes a canister having at least one baffle disposed between two ports and containing a precursor material. The precursor material is adapted to produce a gas vapor when heated to a defined temperature at a defined pressure. The baffle forces a carrier gas to travel an extended mean path between the inlet and outlet ports. In another embodiment, an apparatus for generating gas includes a canister having a tube that directs a carrier gas flowing into the canister away from a precursor material disposed within the canister.

A method to selectively deposit a barrier layer on dielectric material that surrounds one or more metal interconnects on a substrate is disclosed. The barrier layer is selectively deposited on the metal film using a cyclical deposition process including a predetermined number of deposition cycles followed by a purge step. Each deposition cycle comprises alternately adsorbing a refractory metal-containing precursor and a reducing gas on the dielectric material formed on the substrate in a process chamber.

Embodiments of an apparatus for generating a chemical precursor used in a vapor deposition processing system are provide which include a canister having a sidewall, a top, and a bottom forming an interior volume which is in fluid communication with an inlet port and an outlet port. The canister contains a plurality of baffles that extend from the bottom to an upper portion of the interior volume and form an extended mean flow path between the inlet port and the outlet port. In one embodiment, the baffles are contained on a prefabricated insert positioned on the bottom of the canister. In one example, an inlet tube may extend from the inlet port into the interior region and be positioned substantially parallel to the baffles. An outlet end of the inlet tube may be adapted to direct a gas flow away from the outlet port, such as towards the sidewall or top of the canister.
