STRUCTURES FOR PATTERNING SUBSTRATES AND METHODS AND SYSTEMS FOR THEIR MANUFACTURE
Abstract:
Structures, related methods, and related systems for reducing EUV dose. A structure as described herein can comprise a substrate; an electron reflector layer overlying the substrate; and, an extreme ultraviolet (EUV) resist overlying an electron generation layer. The EUV resist is constructed and arranged for absorbing EUV radiation and generating secondary electrons. The electron reflector layer is constructed and arranged for reflecting secondary electrons generated by the EUV resist back towards the EUV resist.
