A Study On Wafer Fabrication On-time Delivery Improvement

In recent years, China domestic notebook industry is developing rapidly, sales quantity and requirement increase a lot. All notebook companies compete to each other. How to increase competitive product by quality improvement and customer satisfaction increasing, cost reduction is key job responsibility to many electronic companies.In this thesis, introduces the concept of DMAIC, define original target of quality improvement project, collect original quality related data, analyze and research by using tools Plato depends on different parts, list mainly defect parts which causes high defect ratio of whole notebook PC. To realize more detail of defect reason, use Plato again to analyze main defect symptom. According to those research result, set as data fundamental of making improvement plan and implement. At same time, monitor and follow up during whole process, adjust on time to make sure of project efficiency.According to example analyze result, research service quality management of Sony VAIO product in China, list exist issues and weakness of procedure, advance improvement scheme and key of project after data collection & research. Implement new project by step. Prove efficient tools of DMAIC and important position of quality management in product manufactory nowadays by example analyzing. High efficient quality management can improve product quality, not only reduce service repair cost and production cost but also reduce cost ratio among sale, increase company profit in the end.
