Abstract: A method for finding the correlation between tool PM (prevention maintenance) and the product yield of the tool is disclosed. The method uses a moving average method to magnify a curve trend that is formed by the product yield data that is captured during a predetermined days before PM and after PM. The magnified curve trend is shown by a Cumulative sum chart. The Cumulative sum chart is analyzed for informing related workers of the effect between the tool PM and the product yield, so as to accurately estimate PM timing. Thereby, via the method, the effect between the tool PM and the product yield may be determined, which serves as an important reference for workers to execute further PM.

Abstract: A graphics processing method using depth parameters for manipulating the inter-overlapping situation between graphic objects and image objects. For each of the graphic objects, the pixels thereof are assigned to respective depth parameters by a three-dimensional transformation procedure. Each of the image objects is assigned to one constant value as its depth parameter. The rendering of the image objects and the graphic objects is performed by sequentially displaying these objects according to their depth parameters. On an overlapping region between these objects, a visible object is selected from the overlapping objects according to the depth parameters assigned to the parts of these objects corresponding to the overlapping region. The resulting image is further processed by processing surface intersections of the overlapping regions of the overlapping objects to smooth the boundary area.
