Wafer Level Packaging

The wafer-level packaging process is an important technology used in semiconductor manufacturing, and how to effectively control this manufacturing system is thus an important issue for packaging firms. One way to aid in this process is to use a forecasting tool. However, the number of observations collected in the early stages of this process is usually too few to use with traditional forecasting techniques, and thus inaccurate results are obtained. One potential solution to this problem is the use of grey system theory, with its feature of small dataset modeling. This study thus uses the AGM(1,1) grey model to solve the problem of forecasting in the pilot run stage of the packaging process. The experimental results show that the grey approach is an appropriate and effective forecasting tool for use with small datasets and that it can be applied to improve the wafer-level packaging process.

Specific Skill

In this paper, case-study evidence of the composition of four robot production systems is provided to reveal the linkages between local, regional, and national social divisions of labour. The relation-specific skill epitomizes the sophisticated procedures used to compose production systems, and the four case studies provide evidence of the communalities and varieties of these procedures. The geography of the interrelationships of the vertical divisions of labour of design-supplied suppliers and of the horizontal division of labour of design-approved suppliers is discussed. The cooperation and competition within this social division of labour allows Japan to function as a flexible manufacturing system.
