New Metric: Cycle Time Impact of Hot Lots (Issue 25.01)

Welcome to Volume 25, Number 1 of the FabTime Cycle Time Management Newsletter. We hope that your 2024 is off to a great start! In this issue, we have an announcement about the release of the new version of FabTime’s software to early adopter sites, as well as the usual highlights from Jennifer’s LinkedIn (Lots of wafer fab-related news has been circulating over the past couple of months). Our software tip of the month is about using the new version of FabTime to generate box plots (a long-time goal of Frank’s). In our subscriber discussion forum, we have detailed responses to last month’s main article about cycle time improvement for 300mm fabs and to a recent subscriber question about managing cycle time for external processes. We so appreciate these subscribers for taking time out of their busy schedules to contribute.

In the previous subscriber discussion forum, we introduced a new metric, requested by a prospective customer, for quantifying the impact of hot lots on regular lot cycle time. After we discussed this metric with our user group, it became clear that a more detailed explanation was needed. In our main article this month we have started with the example from the previous issue and expanded it into a more comprehensive discussion. We think this metric is important because it offers a way to show management the cost of ever-increasing quantities of hot lots in the fab.
