FabTime Dispatch
Enhancing Tool Dispatching Efficiency
Product configurator
Gemini™ MxG5xx
FabTime’s dispatching module is an add-on to our web-based digital dashboard software. At any point, for any tool in your fab, FabTime® will show you the list of all lots qualified to run on that tool. This list will be ordered by the dispatching logic that your site has selected for that tool. This logic can use standard dispatch rules such as Priority-FIFO and Critical Ratio. However, you can also create custom dispatching logic using any combination of dispatch factors.
You can display dispatch lists in FabTime, and/or export them back to your MES. FabTime also includes a dispatch reservation system to hold downstream tools when a lot is started on an upstream tool, as well as dispatch performance reporting.
Advantages
- Ensure wafers needed by management are in fact the wafers that are run, while requiring less manual intervention on the part of management
- Improve delivery to schedule, and the display of performance to schedule
- Document the dispatching logic used by the best operators and make this available to all shifts
