  • Patent number: 9793146
    Abstract: A fab can be constructed as a round or rectangular annular tube with a primary cleanspace located in-between its inner and outer tubes. The fab can be encircled with levels upon which tools can be densely packed while preserving unidirectional air flow. If only tool ports are inside, and robotics are used, primary cleanspace size can be minimized. Highly simplified robotics can be used. Tools can be removed and repaired centrally. A secondary cleanspace can be added for tool bodies. Multilevel construction enhances use of prefabricated units for fab build or maintenance. Curves or folds, applied to a conventional planar cleanroom, can construct a wide range of fab geometries, including a tubular non-annular fab. A fab can also be constructed according to a curved or non-curved sectional cut of an annular tube. A novel fab, of a non-curved section, can include a non-segmented cleanspace or have its tools vertically stacked.

  • Patent number: 9644268
    Abstract: A thermal bridge connecting first and second processing zones and a method for transferring a work piece from a first to a second processing zone by way of the thermal bridge are disclosed. A work piece, transportable from the first to the second processing zone on or above the thermal bridge, is maintained at a temperature between the temperatures of the processing zones. The thermal bridge member features a thermally conductive transport member for the work piece supported over an infrared transmissive member that is insulative to heat conduction and convection. The bridge insulative member extends between the first and second processing zones or between reactors. An infrared radiation beam source emits infrared radiation which passes through the bridge insulative member to the transport member, heating the member. In an alternate embodiment, the transport member may be heated directly. A liner member may be mounted above the bridge member to retain heat.
