Abstract: The present disclosure pertains to embodiments of a semiconductor deposition reactor manifold and methods of using the semiconductor deposition reactor manifold which can be used to deposit semiconductor layers using processes such as atomic layer deposition (ALD). The semiconductor deposition reactor manifold has a bore, a first supply channel, and a second supply channel. Advantageously, the first supply channel and the second supply channel merge with the bore in an offset fashion which leads to reduced cross-contamination within the supply channels.

Abstract: The present disclosure pertains to embodiments of a showerhead assembly which can be used to deposit semiconductor layers using processes such as atomic layer deposition (ALD). The showerhead assembly has a showerhead which has an increased thickness which advantageously decreases reactor chamber size and decreases cycling time. Decreased cycling time can improve throughput and decrease costs.

Abstract: A semiconductor processing method for monitor the dose of a precursor from a solid or liquid source that utilize a caner gas and a semiconductor processing system are disclosed. A pressure or mass-flow controller is used to monitor the carrier as flow into the vessel and mass-flow meter is used to measure that total flow out of the vessel. Based on the difference between these two flows, the precursor flow is obtained and a dose of a solid or liquid precursor to a process chamber and a remaining amount in a source vessel is calculated.

Abstract: An apparatus and method for depositing a transition metal nitride film on a substrate by atomic layer deposition in a reaction space defined by an at least one chamber wall and showerhead is disclosed. The apparatus may include, a substrate support disposed within the reaction space, the substrate support configured for supporting at least one substrate and a temperature control system for controlling a temperature of the at least one chamber wall at those portions of the at least one chamber wall that is exposed to a vapor phase reactant. The apparatus may also include a temperature control system for controlling a temperature of the showerhead, wherein the temperature control system for controlling a temperature of the showerhead is configured to control the temperature of the showerhead to a temperature of between approximately 80° C. and approximately 160° C. The method may include, providing at least one substrate on a substrate support within the reaction space and controlling a temperature of the at least one chamber wall at least at those portions of the at least one chamber wall that is exposed to a vapor phase reactant and controlling a temperature of a showerhead. The method may also include, alternatively and sequentially feeding at least two vapor phase reactants into the reaction space, wherein the temperature of the showerhead is controlled to a temperature between approximately 80° C. and approximately 160° C.
