This technique practically outperforms the conventional optical lithography (diffraction limited optical resolution), exploiting the ultra-short wavelength of the electrons.
WebElectron beam lithography (EBL) is a nano-fabrication technique based on the controlled irradiation of a sample covered with a sensitive resist via a focused beam of electrons. ... allows us to obtain the electron's wavelength (and therefore the nominal resolution of our electron microscope) for different voltages used in the SEM. For a typical ...
The stage moves in between field scans. The electron beam field is small enough that a rastering or serpentine stage motion is needed to pattern a 26 mm X 33 mm area for example, whereas in a photolithography scanner only a one-dimensional motion of a 26 mm X 2 mm slit field would be required. See more Electron-beam lithography (often abbreviated as e-beam lithography, EBL) is the practice of scanning a focused beam of electrons to draw custom shapes on a surface covered with an electron-sensitive film called a See more The primary electrons in the incident beam lose energy upon entering a material through inelastic scattering or collisions with other electrons. In … See more Due to the scission efficiency generally being an order of magnitude higher than the crosslinking efficiency, most polymers used for positive-tone electron-beam lithography will … See more • Electron beam technology • Ion beam lithography • Maskless lithography See more Electron-beam lithography systems used in commercial applications are dedicated e-beam writing systems that are very expensive (> … See more Since electrons are charged particles, they tend to charge the substrate negatively unless they can quickly gain access to a path to ground.
