Electron-beam lithography towards the atomic scale and applications to nano-optics
Electron-beam lithography (EBL) is a high-resolution pattern generation technique widely used in research and development. However, EBL resolution has been limited to 4 nm isolated features and 16 nm periodic structures. Furthermore, the physical mechanisms that limit EBL resolution are not …

Real-time spatial-phase-locked electron-beam lithography
The ability of electron-beam lithography (EBL) to create sub-10-nm features with arbitrary geometry makes it a critical tool in many important applications in nanoscale science and technology. The conventional EBL system is limited by its poor absolute-placement accuracy, often worse than its …

Micro- and nano-electrode arrays for electroanalytical sensing
… were fabricated using electron-beam lithography (EBL). The voltammograms obtained from these arrays exhibited a continual increase in the recorded peak current as the individual electrodes radius was decreased to a value of 110 nm. Since EBL is a slow and costly technique, nanoimprint lithography …
