Paper Abstract

X-ray masks being fragile and expensive, we elaborate a duplication method giving replicas exactly iden-tical or complementary. Using the X-ray transparency of X-ray mask substrates, we make in a simultaneous exposure two replicas of a master-mask, their polarity being determined by that of the two used resists. A careful calculation ensure a correct exposure of the two resist layers by synchrotron radiation. Examples are given for 2 positive or 1 positive 1 negative resists. The polarity inversion of PMMA is also used.
