摘要:
Approaches herein increase a ratio of reactive ions to a neutral species in a plasma processing apparatus. Exemplary approaches include providing a processing apparatus having a plasma source chamber including a first gas inlet, and a deposition chamber coupled to the plasma source chamber, wherein the deposition chamber includes a second gas inlet for delivering a point of use (POU) gas to an area proximate a substrate disposed within the deposition chamber. Exemplary approaches further include generating an ion beam for delivery to the substrate, and modifying a pressure within the deposition chamber in the area proximate the substrate to increase an amount of reactive ions present for impacting the substrate when the ion beam is delivered to the substrate.

According to embodiments, an apparatus and a method for coating a substrate are provided. The apparatus includes a vacuum process chamber. The vacuum process chamber includes a gas inlet assembly and a sputter assembly. The gas inlet assembly includes at least one connector for connecting to one or more process gas sources. The sputter assembly includes a sputter source. The sputter assembly is movable in the vacuum process chamber. The apparatus further includes a controller. The controller is configured for controlling, in dependence of a current position of the sputter source in the vacuum process chamber, at least one of: a flow of a process gas introduced through the gas inlet assembly into the vacuum process chamber, a composition of the process gas introduced through the gas inlet assembly into the vacuum process chamber, and a distribution of the process gas introduced through the gas inlet assembly into the vacuum process chamber. The controller may additionally or alternatively be configured for controlling a gas flow pumped out of the vacuum process chamber.
摘要:
A system and method for processing a workpiece is disclosed. A plasma chamber is used to create a ribbon ion beam, extracted through an extraction aperture. A workpiece is translated proximate the extraction aperture so as to expose different portions of the workpiece to the ribbon ion beam. As the workpiece is being exposed to the ribbon ion beam, at least one parameter associated with the plasma chamber is varied. The variable parameters include extraction voltage duty cycle, workpiece scan velocity and the shape of the ion beam. In some embodiments, after the entire workpiece has been exposed to the ribbon ion beam, the workpiece is rotated and exposed to the ribbon ion beam again, while the parameters are varied. This sequence may be repeated a plurality of times.
