Applying just-in-time in a wafer fab: a case study

Abstract

The successful application of the just-in-time (JIT) manufacturing management philosophy within a wafer fab photoresist wet chemistry area is described. The JIT techniques that were applied included lot-size reduction, setup-time reduction, layout changes for improved work flow, and improved operator flexibility. These set the stage for the implementation of a demand-pull system that resulted in significant decreases in cycle times as well as corresponding decrease in inventory levels. Aspects related to quality improvement as well as other long-term issues are also discussed.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
