The FabTime Cycle Time Management newsletter is a forum for introducing and discussing best practices in wafer fab cycle time management.
Welcome to Volume 19, No. 2 of the FabTime Cycle Time Management Newsletter. In this issue we have community announcements including a call for papers for the e-Manufacturing & Design Collaboration Symposium and about the next Fab Owners Alliance meeting. We have no subscriber discussion at this time (though we do welcome your questions and feedback).
In our tip of the month for this issue we discuss how to add a trendline to any FabTime chart. In our main article we address the use of trendlines more generally for fab performance improvement. We include examples of charts for which trendlines might be particularly useful, and discussions about the value of linear vs. more complex trendlines for day to day performance analysis. Our thanks to members of the FabTime User Group for suggesting trendlines as a topic.
Welcome to Volume 19, Number 1 of FabTime’s Cycle Time Management Newsletter. We hope that everyone had a happy holiday season, and that you are all successfully fending off winter ailments. In this issue of the newsletter we have an announcement about a FabTime webinar that was held in January (and is available for viewing by FabTime customers). We have a subscriber discussion question about hot lots. Our FabTime software tip of the month is about adding a new chart series on the right-hand Y-axis when customizing charts.
In our main article this month, written with Hani Ofeck from Tower Semiconductor, we explore the setting of availability targets. While availability is an important and widely tracked metric in fabs, there is surprisingly little literature regarding the calculation and implementation of availability targets. In our article we share some general thoughts as well as implementation ideas. It is our hope that this will spur further discussion, such that we, the FabTime newsletter community, can improve our collective understanding in this area.
