    摘要: Embodiments of the present invention generally relate to methods for physical vapor deposition processes. The methods generally include synchronizing process chamber conditions with the position of a magnetron. As the magnetron is scanned over a first area of a target, the conditions within the chamber are adjusted to a first set of predetermined process conditions. As the magnetron is subsequently scanned over a second area of the target, the conditions within the chamber are adjusted to a second set of predetermined process conditions different the first set. The target may be divided into more than two areas. By correlating the position of the magnetron with different sets of process conditions, film uniformity can be improved by reducing center-to-edge non-uniformities, such as re-sputter rates which may be higher when the magnetron is near the edge of the target.

    摘要: Embodiments of the present invention generally relate to an apparatus and method for uniform sputter depositing of materials into the bottom and sidewalls of high aspect ratio features on a substrate. In one embodiment, a sputter deposition system includes a collimator that has apertures having aspect ratios that decrease from a central region of the collimator to a peripheral region of the collimator. In one embodiment, the collimator is coupled to a grounded shield via a bracket member that includes a combination of internally and externally threaded fasteners. In another embodiment, the collimator is integrally attached to a grounded shield. In one embodiment, a method of sputter depositing material includes pulsing the bias on the substrate support between high and low values.

    摘要: A plasma sputter chamber and process for sputtering ruthenium and tantalum at low pressure or with self-sustained sputtering (SSS). The source magnetron is strongly unbalanced and of sufficient size to project the unbalanced magnetic field toward the wafer to increase the ionization probability. Sputter etch uniformity is increased by the use of an auxiliary magnet system rotating with the source magnetron but placed towards the center of rotation. It may be a larger, nearly balanced auxiliary magnetron with an outer polarity matching that of the source magnetron or an array of magnets of that polarity. An integrated process includes a directional deposition of the refractory metal and its nitride, a sputter etch, and a flash deposition.
