Patent ID: 7842437

Claim:
A high-resolution, patterned-media master mask comprising: an electron-absorption substrate for absorbing electrons from an electron beam (e-beam) during an e-beam exposure by an e-beam lithography process and suppressing a backscattering of said electrons based on an electron-backscattering-suppressing atomic number associated with a constituent atomic species of said electron-absorption substrate, wherein said electron-absorption substrate comprises a material composed of greater than fifty atomic percent of said constituent atomic species, and wherein said electron backscattering-suppressing atomic number is less than an atomic number eight; and a patterned portion coupled with said electron-absorption substrate, wherein said patterned portion is patterned by said e-beam lithography process, and wherein a resolution of said patterned portion is increased in response to said electron-absorption substrate suppressing said backscattering of said electrons.
