Abstract:
This invention discloses an anti-charging layer for beam lithography and mask fabrication. This invention reduces beam displacement and increases pattern placement accuracy. The process will be used in the beam fabrication of high-resolution lithographic masks as well as beam direct write lithography of electronic devices. The anti-charging layer is formed by the use of metal films bound to metal ligating self-assembled monolayers (SAMs) as discharge layers.
