摘要

半导体晶圆厂中某些快速处理工具组的吞吐量有时会受到FOUP传输系统的限制。交付系统跟不上工具的速度会导致一定的吞吐量损失。这种吞吐量损失可以通过将在制品放置在工具附近来减轻。然而,在制品分期有其局限性。本研究提出了一种克服这些限制的方法,即通过将在制品及时进行调度。

Throughput Optimization of Fast Processing Tools Using a Dispatching Algorithm
Throughput of certain fast processing tool sets in a semiconductor Fab is sometimes constrained by limitations of FOUP delivery system. The delivery system not being able to keep up with the tools result in a certain throughput loss. This throughput loss can be mitigated by staging the WIP close to tools. However, WIP staging has its limitations. This study presents a methodology to overcome these limitations by staging the WIP just in time for dispatching.
