半導體成品測試廠産能規劃研究

Capacity Planning for IC Final Test Plant

摘要


本研究針對半導體成品測試廠之産能規劃問題,提出一套無限産能規劃演算法。此演算法包含四個模組:(1)在製品指派模組、(2)批量投料模組、(3)産能堆疊模組、(4)産能平衡模組。在産品指派模組首先收集在製品之資訊,包含測試批目前加工站別、批量數量...等。針對主生産排程所設定之需求,依産品之週期時間預估測試批於各加工站開工及完工時間。當在製品之數量能滿足主生産排程所設定之需求時,則使用在製品來滿足需求。反之,若無法滿足時則使用批量投料模組進行投料。測試批之開工及完工時間計算完成後,利用産能堆疊模組堆疊機台及治具於每日之産能。若生産資源每日産能堆疊狀況在可接受的範圍內則可依此劇本進行生産。若生産資源每日産能堆疊狀況不盡理想時,可使用産能平衡模組來修改測試批之開工時間,以平衡生産資源之産能。本研究以Visual Basic爲工具,發展一套産能規劃軟體的雛形,並根據工業界實際的資料以驗證本産能規劃系統。藉由實驗設計檢驗産能規劃系統之績效,實驗的結果顯示所發展之産能規劃系統在平衡生産資源於每日産能不均現象時,具有不錯的績效。

並列摘要


In this research, a capacity planning system is proposed for IC final test plants. Four modules are developed; WIP-Pulling Module, Lot Release Module, Workload Accumulation Module, and Workload Balance Module. WIP-Pulling Module is used to calculate lot start time and finish time to meet master production schedule (IVIPS), using WIP information such as current operation station and batch size. When WIP quantity is insufficient, Lot Release Module is called. After calculating the lot start time and finish time, Workload Accumulation Module is used to accumulate the workload of machine and jig in each day. If the workload of machine and jig are unbalanced, Workload Balance Module is used to balance these manufacturing resources. A prototype capacity planning software is developed in Microsoft Visual Basic and industrial data are used to test the performance of the capacity planning system. Based on the design of experiments, simulation results show that the capacity planning system is effective and efficient to balance the workload of manufacturing resources including machine and jig.
