  • Publication number: 20080093022
    Abstract: Methods for transferring substrates in a system with a factory interface robot between at least one FOUP, a buffer coupled to a parasitic device and an inbound and outbound transfer station coupled to a processing tool are provided. In one embodiment, a method for transferring substrates includes transferring a first substrate on an end effector of a robot from a FOUP to a buffer station serving a parasitic device, moving the substrate from the buffer station into the parasitic device, picking up a second substrate on the end effector, compensating for a residence time of the first substrate in the parasitic device, transferring the second substrate to parasitic device from the end effector to the buffer station serving the parasitic device, and picking up the first substrate from the buffer station.

  • Publication number: 20070235344
    Abstract: A method for electrochemical mechanical polishing (ECMP) is disclosed. The polishing rate and surface finish of the layer on the wafer are improved by controlling the surface speed of both the platen and head, controlling the current applied to the pad, and preselecting the density of the perforations on the fully conductive polishing pad. ECMP produces much higher removal rates, good surface finishes, and good planarization efficiency at a lower down force. Generally, increasing the surface speed of both the platen and the head will increase the surface smoothness. Also, increasing the current density on the wafer will increase the surface smoothness. There is virtually no difference in the smoothness of the wafer surface between the center, middle, and edge of the wafer. For copper, removal rates of 10,000 ?/min and greater can be achieved.

  • Publication number: 20070158207
    Abstract: A method for electrochemically processing a substrate is provided. In one embodiment, the method includes performing a conditioning procedure on a processing pad having a plurality of process cells, energizing the process cells by applying a voltage to the conditioned processing pad, placing a substrate having at least a conductive layer disposed thereon on the energized pad, and removing at least a portion of the conductive layer in the energized process cells. In another embodiment, a method for polishing a substrate includes placing an unused conductive pad having a plurality of process cells on a platen of a processing system, breaking in the pad on the platen, energizing the process cells by applying a voltage to the broken-in pad, placing a substrate having at least a conductive layer disposed thereon on the energized pad, and removing at least a portion of the conductive layer in the energized cells.
