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 electron microscope into an electron beam lithography system using relatively low cost accessories (< US$100K). Such converted systems have produced ...
Multibeam developed miniature, all-electrostatic columns for e-beam lithography, that provide a maskless and high throughput platform for writing nanoscale IC patterns seamlessly across full wafers. Arrays of e-beam columns operate simultaneously and in parallel to increase wafer processing speed.
Electron-beam machining is a process in which high-velocity electrons are concentrated into a narrow beam with a very high planar power density. The beam cross-section is then focused and directed toward the work piece, creating heat and vaporizing the material. Electron-beam machining can be used to accurately cut or bore a wide variety of metals.
Massively parallel electron beam lithography has been explored as an alternative to photolithography, and was tested by TSMC, but it did not succeed and the technology from the main developer of the technique, MAPPER, was purchased by ASML, although electron beam lithography was at one point used in chip production by IBM.
Extreme ultraviolet lithography (EUVL, also known simply as EUV) is a technology used in the semiconductor industry for manufacturing integrated circuits (ICs). It is a type of photolithography that uses 13.5 nm extreme ultraviolet (EUV) light from a laser-pulsed tin (Sn) plasma to create intricate patterns on semiconductor substrates.
Etec later merged with ATEQ of Beaverton, Oregon (Portland area), which manufactured laser beam lithography tools. The combined company was named "Etec Systems" and offered a portfolio of lithography relying on both electron and laser beams. These products targeted the photomasks and reticles used in integrated circuit manufacturing.
Etching and deposition each account for 28% of semiconductor cost, totaling 56%, with lithography next at 22%. As Bleeker explained, lithography transfers chip design; but it is etching that ...
Next-generation lithography or NGL is a term used in integrated circuit manufacturing to describe the lithography technologies in development which are intended to replace current techniques. Driven by Moore's law in the semiconductor industries, the shrinking of the chip size and critical dimension continues.
