In the paper, the principle of Electron Beam Lithography（EBL） and the application in micro-and nano-fabrication are presented. At first, operating principle of EBL system is overviewed. Then a detailed discussion on key process in EBL is made, such as the choice of Resist, optimized lift-off process and modification of proximity effect. In the final part, several examples on biological medicine and silicon photonics applications are added. The EBL is now attaching increasingly more attention due to its great potentials in the days to come.
