WebA schematic of an IPL system is shown in Fig. 12.20. Ions with a small spread in energy are produced by a recently developed ion source. 2, 3 Electrostatic lenses are then used to produce a uniform beam of ions that covers the area of the mask. Beam energies are typically = 250 keV. 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 selective removal of either the exposed or non-exposed regions of the resist by immersing it in a s…

WebAn additional method of lithography is the use of ion beams. The wafer can be exposed with a photomask or, like in electron beam lithography, without a mask. In case of hydrogen ions the wavelength is about 0.0001 nm. Other elements allow a direct doping of the wafer without the use of masking layers. Photoresist
