    摘要: Embodiments of the invention provide chemical precursor ampoules that may be used during vapor deposition processes. In one embodiment, an apparatus for generating a chemical precursor gas used in a vapor deposition processing system is provided which includes a canister having a sidewall, a top, and a bottom forming an interior volume and a solid precursor material at least partially contained within a lower region of the interior volume. The apparatus further contains an inlet port and an outlet port in fluid communication with the interior volume and an inlet tube connected to the inlet port and positioned to direct a carrier gas towards the sidewall and away form the outlet port. In one example, the solid precursor contains pentakis(dimethylamido) tantalum (PDMAT). In another example, the apparatus contains a plurality of baffles that form an extended mean flow path between the inlet port and the outlet port.

    摘要: 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.

    摘要: A method of forming barrier layers in a via hole extending through an inter-level dielectric layer and including a preformed first barrier coated onto the bottom and sidewalls of the via holes. In a single plasma sputter reactor, a first step sputters the wafer rather than the target with high energy ions to remove the barrier layer from the bottom of the via but not from the sidewalls and a second step sputter deposits a second barrier layer, for example of Ta/TaN, onto the via bottom and sidewalls. The two steps may be differentiated by power applied to the target, by chamber pressure, or by wafer bias. The second step may include the simultaneous removal of the first barrier layer from the via bottom and sputter deposition of the second barrier layer onto the via sidewalls.
