25 August 2017 Electrostatic microcolumns for surface plasmon enhanced electron beamlets
Author Affiliations +
Microcolumns are widely used for parallel electron-beam lithography because of their compactness and the ability to achieve high spatial resolution. A design of a large array of electrostatic microcolumns for our recent surface plasmon enhanced photoemission sources is optimized numerically. Because of the compactness, one million of microcolumns can be put within 1 cm2 area. To avoid the trade-off between resolution and throughput, each microcolumn has one beamlet and there is no crossing point between any of the beamlets. An aperture self-aligned fabrication process is developed to make the optimized microcolumns.
