FabTime Capacity Planning Module
|
Given a target product mix, do we need any new tools?
|
|
Given the tools that we have, and the products that we are running, how many wafers can we expect to produce?
|
|
Given our existing set of products and tools, what happens if the product mix changes? Where can we expect bottlenecks? |
FabTime’s capacity planning module leverages the data
already stored in the FabTime digital dashboard software, to
make it easier to build capacity planning scenarios. The only
required manual inputs are:
|
Weekly ships per product.
|
|
Product line yield percentages.
|
FabTime uses route information from the fab MES and calculates UPH data
(tool speed) based on actual performance. FabTime also uses tool uptime
performance to estimate availability (though this can be overridden).
These inputs are used to generate predicted utilization percentages for
each capacity type. Detailed intermediate calculations (UPH, tool productive
time, tool rework percentage, etc.) are also available (an example for one tool
is shown below). All outputs can be easily exported to Excel.
FabTime Capacity Planning Module Benefits
|
Eliminate the need to maintain offline capacity planning models.
|
|
Automatically update capacity planning data to reflect new conditions (process flows, tool uptime characteristics).
|
|
Quickly run scenarios to anticipate (and avoid) bottlenecks caused by product mix changes.
