One design of multi-function LIGA beamline has been reported. In this design, two plane mirrors and a series of filters have been employed. One can choose the spectrum range of X-ray easily according to the exposure requirement by adjusting the grazing angle of mirrors and the thickness of filters. And the spot size in the horizontal direction is up to 120mm, which is large enough for exposing 5 inch silicon slice. The typical exposure time is about 1.2h, 1.8h, 0.5h, corresponding to PMMA thickness of 500μm, 200μm, 20μm, respectively.
