摘要

Microelectromechanical Systems, MEMS, are the embodiment of the sophisticated, diverse, fertile and multidisciplinary technologies stemming from microelectronics miniaturization. Potentially, this miniaturization increases the performance of spacecraft and enables new applications in space. Taken to its extreme, it allows for entirely miniaturized spacecraft, requiring a less costly launch, and the possibilities of finding an earlier time slot and putting the spacecraft into service earlier. This implies large manufacturing volumes and efficient processing, and hence necessitates a better understanding of the complexity of microfabrication. This is particularly important when adding design demanding and cost driving requirements. Microfabrication differs from other types of fabrication in terms of the numerous processes involved, and their great variety, partly explaining the difficulty of planning and controlling the manufacturing, especially in terms of costs and lead times. In this work, a tool for estimating costs and lead times for manufacturing of integrated MEMS is described and evaluated. It takes critical parameters, such as process and equipment capacity, operating costs, need for labour attendance, batch sizes, etc., into account. As an illustrative and verifiable example, the processing of a pressure sensor is studied. The impact of component size, yield and the manufacturing scheme on lead time and cost is demonstrated. In addition, the time savings from letting individual operations overlap with each other are visualized. Hopefully, the power of this tool is revealed in this work, and hopefully it will lower the threshold to MEMS- in particular for space technology applications.
