  • Publication number: 20230170231
    Abstract: Exemplary substrate processing systems may include a factory interface and a load lock coupled with the factory interface. The systems may include a transfer chamber coupled with the load lock. The transfer chamber may include a robot configured to retrieve substrates from the load lock. The systems may include a chamber system positioned adjacent and coupled with the transfer chamber. The chamber system may include a transfer region laterally accessible to the robot. The transfer region may include a plurality of substrate supports disposed about the transfer region. Each substrate support of the plurality of substrate supports may be vertically translatable. The transfer region may also include a transfer apparatus rotatable about a central axis and configured to engage substrates and transfer substrates among the plurality of substrate supports. The chamber system may also include a plurality of processing regions vertically offset and axially aligned with an associated substrate support.

  • Patent number: 7819079
    Abstract: The present invention generally provides an apparatus and method for processing substrates using a multi-chamber processing system (e.g., a cluster tool) that is easily configurable, has an increased system throughput, increased system reliability, improved device yield performance, a more repeatable wafer processing history (or wafer history), and a reduced footprint. In one embodiment, the cluster tool is adapted to perform a track lithography process in which a substrate is coated with a photosensitive material, is then transferred to a stepper/scanner, which exposes the photosensitive material to some form of radiation to form a pattern in the photosensitive material, and then certain portions of the photosensitive material are removed in a developing process completed in the cluster tool.

  • Publication number: 20080051929
    Abstract: Methods and apparatus for increasing the processing throughput of multiple lots of semiconductor wafers through a cluster tool while maintaining a constant wafer history for each lot are provided. A first lot of wafers containing one through n-th wafers is introduced into a cluster tool containing one or more processing chambers. The first lot of wafers is processed for a first time period. A second lot of wafers containing one through n-th wafers is introduced into the cluster tool prior to completion of the first time period, wherein the second lot is introduced so as to minimize a time gap between the n-th wafer of the first lot of wafers and the first wafer of the second lot of wafers while maintaining a first constant wafer history for each wafer within the first lot and maintaining a second constant wafer history for each wafer in the second lot.

  • Publication number: 20080051930
    Abstract: Methods and apparatus for improving substrate throughput prior to processing a plurality of substrates in a cluster tool having a plurality of processing chambers and at least two robots are provided. The method comprises developing a process sequence, storing the process sequence on a storage device, and transferring the process sequence from the storage device to a controller in communication with the cluster tool. The process sequence comprises depositing one or more uniform resist layers on the surface of the plurality of substrates, transferring the plurality of substrates out of the cluster tool to a separate stepper or scanner tool to pattern the surface of the plurality of substrates by exposing the resist layer to a resist modifying electromagnetic radiation, and then developing the patterned resist layer.

  • Publication number: 20080014058
    Abstract: Methods and apparatus for processing substrates using a multi-chamber processing system (e.g., a cluster tool) that has an increased system throughput and repeatable wafer processing history are provided. In one embodiment a first substrate is transferred from a first position to a second position and then the first substrate is transferred from the second position to a third position using a first robot. A second substrate is transferred from a first position to a second position and then the second substrate is transferred from the second position to a third position using a second robot. The movement of the first and second robots is synchronized so that the movement from the first position to the second position by the first and second robot is performed within a first time interval.
