本研究以國內CMOS 影像感測器製造之半導體光學產業為實例，隨著智慧型手機硬體規格更新速度日漸加快及汽車應用系統之普及，CMOS 影像感測器產品生命週期也逐漸縮短，因此，個案公司身為CMOS 影像感測器製造領導廠商之一，持續致力於縮短交期與降低生產成本來因應市場快速的變化。
半導體製造過程相當複雜，從原材料矽晶圓開始，需經過沉積、擴散、金屬濺鍍、塗佈光阻、蝕刻等一連串的製造程序，最後切割成晶粒並完成封裝。個案公司希望藉由導入自動化專案之派工指令自動化及載具搬運自動化，以達到精準派工來縮短產品生產週期，同時逐步降低人工搬運的傳送方式，減少因人為操作失誤的風險，使人力運用上更加彈性。
本研究運用精實手法，以協助評估導入自動化專案的成效，透過繪製後的價值溪流圖，可以清楚地辨識出個案公司生產線浪費之所在。模擬技術是一種允許更改虛擬生產線的簡單方法，進而可以分析在實際實施改善活動之前的任何改變對其影響的程度及結果，避免不必要的成本耗費，並達到節省時間。比較現況價值流圖與未來價值流圖發現，總作業時間改善幅度達2.3%；而在導入自動化搬運系統目標區域之人力需求評估階段，輔以模擬技術作為改善方向之參考，實際導入搬運自動化後，由改善前的6員配置，縮減至改善後2員，人力改善幅度達67%。
本研究結果顯示，運用價值溪流圖(VSM)結合模擬技術對於個案公司生產過程中之決策來說是一套可行及良好的研究方法。

In this case study, a CMOS factory which is listed in Taiwan as an example. According to the CMOS image sensor production and marketing research, the high-end smart phone shipment is gradually increased and the popularity of automotive application systems.
The semiconductor manufacturing process is quite complicated. From the raw material to the wafer shipment, a series of manufacturing processes such as deposition, diffusion, metal sputtering, coating, exposure, etching, and so on. In order to shorten the product’s lead time and reduce the cost of production, the main purpose in the case company is use lean as the research tool to improve the CMOS factory procedures by the implement of real-time dispatching and automation of mobile robot handling. Besides, it is expected that the automation will help to reduce the manual handling and decrease the risk of human error.
By drawing the current and the future state value stream mapping, it was possible to identify the waste present in the process of this case study. Simulation is the simple way to allowed any chang in the virtual production line. And it is possible to analyze the impact of changes before actually implementing the lean action of this case study to avoid the unnecessary costs, and save the more time to this case study. It is clear that adapted value stream mapping (VSM) and simulation application, results into the main benefits include the lead time improved 2.3%, and also productivity increased over 60% by saving 2 manpowers from 6 on target area (development).
The results in this paper showed that value stream mapping (VSM) combined with the simulation is a good tool in the decision-making for change in production process to this case study.
