Electron beam lithography ( EBL ) is a method of etching semiconductors at resolutions smaller than a micron.

Electron beam processing is used to irradiate materials in order to change their physical properties or sterilize medical and food products.

Electron beam lithography is also important commercially, primarily for its use in the manufacture of photomasks.

Electron beam lithography as it is usually practiced is a form of maskless lithography, in that a mask is not required to generate the final pattern.

Electron beam lithography has the disadvantage of being much slower than photolithography.

Electron beam lithography ( often abbreviated as e-beam lithography ) is the practice of scanning 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 ").

Electron beam tomography is a specific form of CT in which a large enough X-ray tube is constructed so that only the path of the electrons, traveling between the cathode and anode of the X-ray tube, are spun using deflection coils.

Electron beam welding ( EBW ) is a fusion welding process in which a beam of high-velocity electrons is applied to the materials being joined.

Electron excitation is the movement of an electron to a higher energy state.

The title of his doctoral dissertation is " Electron impact excitation of heavily ionized atoms ".

The Acorn Electron is a budget version of the BBC Micro educational / home computer made by Acorn Computers Ltd.

There are at least 500 known games for the Electron and the true total is probably in the thousands.

If Acorn had thought to include this small modification in the original Electron design it is likely the machine would have had a much greater impact as it would have nearly doubled the amount of motion possible in games and saved modes 0 – 3 ( including the only 16 colour mode ) from being nearly useless due to contended memory timings.

The Electron is widely misquoted as operating at 1. 79 MHz after measurements derived from speed testing against the thoroughly 2 MHz BBC Micro for various pieces of ' common software '

Notable popular games particularly associated with the Electron include: Crystal Castles ( video game ) | Crystal Castles is an example of a popular arcade game officially ported to the Electron ( US Gold ).

Electron software is predominantly archived in the UEF file format.

Electron degeneracy pressure is a quantum-mechanical effect arising from the Pauli exclusion principle.

Electron gas can undergo plasma oscillation, which is waves caused by synchronized variations in electron density, and these produce energy emissions that can be detected by using radio telescopes.

The Transmission Electron Aberration-corrected Microscope is capable of sub-0. 05 nm resolution, which is more than enough to resolve individual atoms.

Electron counting is a formalism used for classifying compounds and for explaining or predicting electronic structure and bonding.

# Electron in the initial state is represented by a solid line with an arrow pointing toward the vertex (→•).

# Electron in the final state is represented by a line with an arrow pointing away from the vertex: (•→).

Electron capture is the main decay mode for isotopes lighter than the < sup > 51 </ sup > V.

* July 10 – Donald Crowhurst's trimaran Teignmouth Electron is found drifting and unoccupied.

Electron paramagnetic resonance, otherwise known as Electron Spin Resonance ( ESR ) is a spectroscopic technique similar to NMR, but uses unpaired electrons instead.

Of the capabilities present in the BBC Micro but absent from the Electron, the teletext-style mode 7 was particularly conspicuous because of the very low memory usage in that mode ( just less than 1 kB ) and the high number of BBC programs that used it.

Although cheap and effective in enabling use of some software that only used official ROM entry points for text output, this solution proved very slow because the Electron had to be placed into an 80-byte-pitch display to be able to get anywhere near to reproducing mode 7 and the CPU spent a lot of time drawing approximations of mode 7 characters and graphics that in a hardware solution would be achieved without any CPU processing.

Electron beams are used in welding, which allows energy densities up to across a narrow focus diameter of and usually does not require a filler material.

Electron microscopes are used to observe a wide range of biological and inorganic specimens including microorganisms, cells, large molecules, biopsy samples, metals, and crystals.

The Deutsches Elektronen-Synchrotron ( German Electron Synchrotron ), commonly abbreviated DESY, is a national research center in Germany which operates particle accelerators used to investigate the structure of matter.

Electron transport chains are the cellular mechanisms used for extracting energy from sunlight in photosynthesis and also from redox reactions, such as the oxidation of sugars ( respiration ).

Electron microscopy and serologic studies were used to confirm that the disease was human monkeypox.

Electron diffraction is most frequently used in solid state physics and chemistry to study the crystal structure of solids.

Electron ionization and chemical ionization are used for gases and vapors.

These cards are similar to closed system prepaid cards, but are endorsed by a retail electronic payments network such as Visa, Visa Electron, MasterCard, or Maestro and can, unlike gift cards, be used anywhere debit cards with the same logo may be used.

Electron ionization is widely used in mass spectrometry, particularly for organic molecules.

Electron tube can be used to describe either of two things:

Electron pairs are therefore considered lone pairs if two electrons are paired but are not used in chemical bonding.

Electron transfer is used in all respiratory functions as well as photosynthesis.

Electron microscopy or EM can be used to study the detailed microarchitecture of tissues or cells.

Acorn Computers used several ULA chips in the BBC Micro, and later managed to compress almost all of that machine's logic into a single ULA for the Acorn Electron.

They are also used to make HEMTs ( High Electron Mobility Transistors ), which are used in low-noise electronics.
