[0009] 上述对中块主体上的观察孔的位置是经过精心设计的，当对中块主体的三个挡边与真空机械手手指对齐时，观察孔的圆心也就是手指上放晶圆时的圆心。 [0009] the position of the observation holes in the block body is carefully designed, when the three ribs of the block body is aligned with the vacuum robot fingers, i.e. the center of the peephole put the finger on the wafer center. 在定位时，使对中块的观察孔分别与EFEM手指上的圆环，加热盘定位工装上的圆孔同心，则定位完成。 When positioning the viewing aperture of the block respectively the EFEM ring finger, the circular heating plate positioned concentrically tooling, the positioning is completed.
