晶圓廠瓶頸機台的產能分析與派工法則

Capacity Analysis and Dispatching Rules of Bottleneck Machinery in Semiconductor Foundry

摘要


半導體是一高技術及高投資的產業,而隨機讀取記憶體(DRAM)更因產品具有高標準化的特性,致使各DRAM專業製造廠都以最新的機器與製程技術投入生產。然而,當一座以生產DRAM之老舊晶圓廠,在機器與製程技術不再具有競爭力時,必將其由單一DRAM產品轉為生產具有較高獲利的低標準化產品,而其生產型態勢必也從少樣多量的方式,轉換為多樣少量的生產模式。所以企業在追求最高利潤下,如何在多樣少量的生產模式中獲取最佳績效,必將是一重要的課題。但由於半導體產品因製程世代與製程產品的不同,即使相同製程技術條件下,不同產品間的規格亦存在極大的差異,故本研究將以CCR多樣少量的模式下,提出CCR機台的產能上與使用率之損失分析模式,並且以限制理論修正CCR相關工作站的派工法則,使CCR機台的產能與使用率受到保護,獲得晶圓廠轉換之最佳目的。

並列摘要


The semiconductor is a highly specialized and investment intensive industry, and many of the Dynamic Random Access Memory (DRAM) manufacturers utilize the state-of-the-art machines and processes to the production because of its standard characteristics. However, when the processes and production tools are outdated, it is necessary to transfer those less profitable DRAM products to less standardized products with higher return. As a result, the manufacturing will be shifted to large volume and less variety from small volume and large variety; the operational performance then becomes the core issue for enterprises. Unfortunately, the production processes are highly interrelated with the products of different generation. The objective of the study is to develop a revised dispatching rule and a constrained capacity resource (CCR) model to protect the capacity of the CCR, and therefore, to obtain better processes transformation performance.
