Abstract: A ring storage station used for delivering a consumable part to a substrate processing system includes a housing that includes a base plate and a rotating plate disposed over the base plate. An end-effector opening is disposed at a first side of the housing and a service window opening is disposed at a second side of the housing. A set of finger support structures is connected to the rotating plate. Each finger support structure includes a support column and support fingers disposed thereon. At least two of the set of columns have support fingers with index pins to radially align consumable parts when disposed in the ring storage station. In one configuration, consumable parts may be designed to match the rotation angle engagement to ensure catching the angle alignment between ring storage and process module.

Abstract: A system includes a robot configured to transfer either one of a substrate and an edge ring within a substrate processing system, a substrate aligner configured to adjust a rotational position of either one of the substrate or the edge ring relative to an end effector of the robot, and a carrier plate configured to support the edge ring. The robot is configured to retrieve the carrier plate with the end effector, retrieve the edge ring using the carrier plate supported on the end effector, and transfer the carrier plate and the edge ring to the substrate aligner.

Abstract: A lifting assembly can lift a substrate from a substrate support and transport the substrate. The lift assembly has a hoop sized to fit about a periphery of the substrate support, and a pair of arcuate fins mounted on the hoop, each arcuate fin comprising a pair of opposing ends having ledges that extend radially inward, each ledge having a raised protrusion to lift a substrate so that the substrate contacts substantially only the raised protrusion, thereby minimizing contact with the ledge, when the pair of fins is used to lift the substrate off the substrate support. The lifting assembly and other process chamber components can have a diamond-like coating having interlinked networks of (i) carbon and hydrogen, and (ii) silicon and oxygen. The diamond-like coating has a contact surface having a coefficient of friction of less than about 0.3, a hardness of at least about 8 GPa, and a metal concentration level of less than about 5×1012 atoms/cm2 of metal.

Abstract: A physical vapor deposition chamber is employed to sputter-deposit a layer of material, such as a tantalum or tantalum nitride barrier layer, in a via formed on a semiconductor substrate. After the sputter-deposition step, a second processing step is performed in which material from the barrier layer is back-sputtered from the bottom wall of the via. The second step is performed at a high pedestal bias and with substantial power applied to the sputtering target. The power applied to the sputtering target in the second step may be at a higher level than the power applied to the sputtering target in the first step. Numerous other aspects are provided.

Abstract: A method of improving the temperature control of a clamped substrate mounted on a substrate support that is biased, the substrate support having a passage therethrough to permit a flow of backside gas for heating or cooling the substrate, whereby the pressure of the backside gas is maintained at at least 15 torr. A high gas pressure improves the thickness uniformity of processing across the substrate. For plasma deposition of sputtered seed layers, the morphology of the seed layer is improved near the edge of the substrate and the uniformity of the layer across the substrate is also improved.

Abstract: A magnetron sputter reactor for sputtering deposition materials such as tantalum, tantalum nitride and copper, for example, and its method of use, in which self-ionized plasma (SIP) sputtering and inductively coupled plasma (ICP) sputtering are promoted, either together or alternately, in the same chamber. Also, bottom coverage may be thinned or eliminated by ICP resputtering. SIP is promoted by a small magnetron having poles of unequal magnetic strength and a high power applied to the target during sputtering. ICP is provided by one or more RF coils which inductively couple RF energy into a plasma. The combined SIP-ICP layers can act as a liner or barrier or seed or nucleation layer for hole. In addition, an RF coil may be sputtered to provide protective material during ICP resputtering.

Abstract: A multi-step process for the deposition of a material into high aspect ratio features on a substrate surface is provided. The process involves depositing a material on the substrate at a first pressure for a first period of time and then depositing the material on the substrate at a second pressure for a second period of time. Modulation of the pressure influences the ionization and trajectory of the particles, which are ionized in a plasma environment. The method of the invention in one aspect allows for optimum deposition at the bottom of a high aspect ratio feature during a high pressure step and increased deposition on the sidewalls of the feature during at least a low pressure step.

Abstract: An improved system for performing plasma enhanced PVD of copper, aluminum, tungsten or other metallic material is disclosed. The system has markedly improved performance in the critical area of unwanted in-film particle deposits. The improved performance is provided by lowering the operating temperature of the RF coil used in the plasma enhanced PVD system and by carefully smoothing the outer surface of the RF coil. High conductivity material in the coil supports, increased contact area between the coil supports and the RF coil, and the use of active cooling of the coil further enhance the performance of the system.
