使用Web Services 於面板廠之MES與SPC系統整合之改善

Abstract

由於全球面板產業的競爭相當激烈，為了提升競爭力-提高產品良率、降低生產成本，以及增進生產效率，生產管理以及品質管理變得格外重要。面板生產過程使用複雜的物理與化學製程，須有多重的量測站點確認生產製程前後的品質，並運用統計製程管制(Statistic Process Control，SPC)的手法來監控製程品質的變化趨勢，以掌控生產機台的穩定度。本研究利用MES 之出站作業(trackout)與SPC系統之製程管制的整合流程，達成提高生產效率，以及產品製程品質控管。生產人員執行出站作業時，其系統回應時間之長短影響生產人員的生產效率與製程品質檢查的即時性。為了改善此現象，本研究以企業流程再造工程之方法，於MES與SPC系統整合流程中，找出影響系統回應時間的主要因子，並評估軟體技術以重新設計系統架構，改善系統回應時間。此研究成果，也提供中小型面板製造商，或是研發實驗機構，在整合MES之出站作業以及SPC系統品質檢驗之流程與系統架構做為參考。

The Flat Panel Display(FPD) Industy is suffering the firece competition. In order to improve the competence – higher product yield, lower product cost and enhance the production efficiency, the production and quality management becomes extremely important. The FPD production process using complicate physical and chemical process, must have many metrology steps to validate the process quality before and after the process steps, and use the statistic process control(SPC) methodology to monitor the process quality trend, in order to control the stability of the production equipment. This case study is a demonstration to integrate the MES track-out process and process quality control of the SPC system, to improvement the production efficiency and the product process quality control. When the production staff executes the track-out order in the MES, the system response time would impact the production efficiency and process quality control. To improve this, the case study leverages the methodology of the business process reengineering, to find out the main factors which impact the system response time. And evaluate the software technology to redesign the system integration architecture, in order to shorten the response time. This architecture framework could also be helpful for the small-medium size panel makers and the R&D institution to integrate the MES track out step with the SPC quality check step.
