Term (Index) Definition
generation  process of free charge carriers formation in semiconductor; in band-to-band generation electron acquiring energy in excess of energy gap moves from the energy state in the valance band to the energy state in the conduction band leaving free hole in the valance band; formation of electron-hole pair.
recombination  process resulting in annihilation of free charge carriers in semiconductor; reversal of the generation process; typically electron recombining with hole looses energy and moves from the conduction band to valence band.
Term (Index) Definition
carrier generation  the process of creating electron-hole pairs in semiconductor.
Term (Index) Definition
generation current  current resulting from the generation of electron-hole pairs in the space charge region of the reverse biased p-n junction.
Term (Index) Definition
generation lifetime  average time needed to generate electron-hole pair
Term (Index) Definition
nanotechnology, new generation  scientific and technical solutions which will allow progress in atomic-level manipulation of materials geared primarily toward continued improvement in the performance of digital (computational) systems; will be needed once all means and ways of “conventional nanotechnology” will be fully exploited; represents “bottom-up” approach to device processing; explores any system existing in nature that is potentially capable of a binary state which can then be converted into electronic “on” and “off” state; e.g. spin of an electron, properties of selected molecules and molecular systems, etc.; also explores nano-scale material configurations which can be potentially used to reproduce transistor switching action; e.g. carbon and silicon nanotubes and nanowires, quantum dots, etc.; from the point of view of computational functions “new generation nanotechnology” does not offer winning solutions yet, but evolution of this very broad scientific and technical domain will certainly bring about spectacular progress in many other aspects of human endeavor.
bottom-up processing  way of building functional structures on semiconductor substrates which relies on self-assembly of molecules and self-patterning taking place at the surface of the substrate.
Term (Index) Definition
NGL, Next Generation Lithography  meaning of the term evolves with time following changes in the lithographic techniques.
Term (Index) Definition
pattern generation, generator  transfer of design layout from computer files onto the mask by means of direct-write electron beam lithography.
