We report on the resolution limits of Electron Beam Lithography (EBL) in the conventional polymethylmethacrylate (PMMA) organic resist. We show that resolution can be pushed below 10 nm for isolated features and how dense arrays of periodic structures can be fabricated at a pitch of 30 nm, leading to a density close to …

WebElectron Beam Lithography (e-beam lithography or EBL) is an advanced lithography technology for creating ultrafine patterns (as small as 5nm) by using a focused electron beam. Derived from the scanning electron microscope, the technique in brief consists of scanning a beam of electrons in the desired pattern across a surface covered with an e ... Web3.6 Electron-beam lithography. Electron-beam (e-beam) lithography is a maskless lithography method that utilizes an electron gun from a scanning electron microscope to pattern nanoscale features on a substrate surface. As opposed to photolithography, the resolution of e-beam lithography can reach precision levels down to 1 nm.
WebMar 22, 2024 · E-beam lithography is sometimes known as maskless lithography or direct-write lithography. The e-beam directly writes patterns on a wafer at resolutions … 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 resist (exposing). The electron beam changes the solubility of the resist, enabling … See more Electron-beam lithography systems used in commercial applications are dedicated e-beam writing systems that are very expensive (> US$1M). For research applications, it is very common to convert an 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. For a high-energy beam incident on a silicon … See more To get around the secondary electron generation, it will be imperative to use low-energy electrons as the primary radiation to expose resist. … See more The primary electrons in the incident beam lose energy upon entering a material through inelastic scattering or collisions with other electrons. In such a collision the momentum transfer from the incident electron to an atomic electron can be expressed as 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 • Photolithography See more
