Paper Abstract

SCALPELTM, (scanning with angular limitation projection electron-beam lithography) is a projection electron-beam lithography technique with the potential for high resolution and throughput that can extend the state of lithography below 0.18 micrometer. The success of this technology, developed at AT&T , is directly connected to the ability to manufacture a robust SCALPEL mask blank. An error budget analysis has been performed on the SCALPEL mask. This analysis has generated specific requirements for the mask blank. In this paper we discuss their impact on the mask blank fabrication and show that we are making good progress towards meeting these requirements.
