Abstract
The sales of new products have become a major part of a firm’s revenue. However, the success of new products mainly depends on the new product development processes. The companies in high-tech industry face a rapidly changing and competitive environment in technology development and market demand. They not only have to focus on product innovation, but also the development and introduction of new manufacturing technologies to obtain more orders. To have a systematic method and tool for new product development in high-tech industry, this research proposed a procedure which is modified from the new product development process of advanced product quality planning (APQP) in ISO/ TS 16949. Before the process failure mode and effects analysis (PFMEA), we evaluate the production performance of process-related machines to form a golden line and combine product specification with design failure mode and effects analysis (DFMEA) and PFMEA to monitor critical parameters. This study applied the proposed procedure to a TFT-LCD manufacturing firm, in which a four-mask technology is introduced to the TFT Array process in the new product development phase. The experimental results showed that the proposed procedure reduces the time to market from 130 days to 100 days and improves the first pass yield (FPY) in TFT Array and Cell processes. Our proposed procedure can construct quality control system, increase first pass yield in each manufacturing process and reduce the time to market for new product.
