Existing research about automated wafer transport management strategy for semiconductor manufacturing equipment was mainly focused on dispatching rules which is optimized to specific system layout, process environment or transfer patterns. But these methods can cause problem as like requiring additional rules or changing whole transport management strategy when applied to new type of process or system. In addition, a lack of consideration for interconnectedness of the added rules can cause unexpected deadlock. In this study, in order to improve these problems, propose dynamic priority based transfer job decision making algorithm which is applicable with regardless of system lay out and transfer patterns. Also, extra rule handling part proposed to support special transfer requirement which is available without damage to generality for maintaining a consistent scheduling policies and minimize loss of stability due to expansion and lead to improve productivity at the same time. Simulation environment of Twin-slot type semiconductor equipment was built In order to measure performance and examine validity about proposed wafer scheduling algorithm.

In recent years, technologies have been developed to capture omnidirectional images by using two or more cameras equipped with wide-angle lenses. In omni-directional images, all directions can be seen, so that monitoring effect can be maximized. Obtaining an omni-directional image through a wide-angle lens causes distortion, which makes it difficult to be applied on intelligent algorithm based on image processing. In order to solve this problem, it is generally necessary to image processing for a long time. In this paper, we propose an accelerated intelligent algorithm for distorted images acquired through a wide-angle lens. Through the proposed algorithm, it is possible to render intelligent image analysis results in real time. We have a plan to study on the method of high resolution technology in the future.
