PowerPoint Presentation Last modified by: Electron Beam Lithography is a specialized technique for creating extremely fine patterns (~ 50 nm). - Electron beam lithography (often abbreviated as e-beam lithography) is the practice of emitting a beam of electrons in a patterned fashion across a surface covered with a film (called the resist), ("exposing" the resist) and of selectively removing either exposed or non-exposed regions of the resist ("developing"). We investigated electron-beam lithography with an aberration-corrected scanning transmission electron microscope. In traditional optical microscopes, the detector sees the light in the far field region. All Time. Derived from the early scanning electron microscopes, the technique consists of scanning a beam of electrons across a surface covered with a resist film sensitive to those electrons, thus depositing energy in the desired pattern in the resist film.
