Abstract

Abstract This paper focuses on the two-layer RIE PCM system [1] using both DUV and E-Beam exposures. An organosilicon polymer (SNR M2 from TOYO SODA) serves as top image resist and is spin coated over a thick crosslinked novolak layer (HPR 204). This system allows a very high aspect ratio image to be attained which is an essential characteritic for obtaining high resolution.
