We have developed a new method for fabricating a silicon submicrometer shadow mask for nanofabrication in ultra-high vacuum. Combining KOH anisotropic wet etching, electron beam lithography, reactive ion etching and focused ion beam techniques, a pattern size of 2.5×2.5 mm2 and opaque part about 1 μm can be obtained.
