Definitie EN: a cathode consisting of a metal base coated with alkaline-earth oxides as the emissive material

Definitie EN: the production of a layer of oxide on the surface of a semiconductor piece,achieved by oxidation of the semiconductor itself(by heating in suitable atmosphere),by deposition of oxide material(not necessarily self oxide),by sputtering etc.,or by dissociation of a suitable gas

Definitie EN: a chemical etching system devised to remove material from a heterogeneous system at different rates for different components

Definitie EN: the ratio of the equilibrium density of particular impurity atoms in a semiconductor to the equilibrium density of those impurity atoms in the oxide at the interface

Definitie EN: the deterioration of a tape by disintegration of its magnetic coating

Definitie EN: a silicon oxide,powdered or solid,that has absorbed a sufficient density of impurity atoms to be used as a source of impurities in a solid-state diffusion process

Definitie EN: a charge trapped in the insulator of an MIS device that cannot move to the semiconductor material

Definitie EN: outdiffusion of impurity atoms from a semiconductor surface through an oxide layer grown on that surface,by virtue of the high diffusivity of impurity-atoms through the oxide layer,or of the low segregation-coefficient at the semiconductor-oxide interface

Definitie EN: shape of the intermediate region between unetched oxide and unoxidized silicon surface at the edge of an oxide layer prepared as a diffusion mask on a silicon surface

Definitie EN: inversion layer on the surface of a p-type semiconductor piece,produced as a result of the effect of an oxide film in bending down the energy-bands in the surface region

Definitie EN: stress in surface layers of a silicon piece on which thermal oxide is formed,resulting from the difference in thermal expansion coefficients between silicon and silicon oxide,cooling from oxidation temperature introducing tensile stress into the silicon and compressive stress into the oxide

Definitie EN: solid-state diffusion operation in which drive-in diffusion is carried out after deposition,the diffusion atmosphere being oxidizing so that an oxide layer forms over the deposited surface,sealing in the deposited impurities and sealing out further impurities

Definitie EN: an oxygen-rich compound,readily oxidising substances with which it is brought into contact

Definitie EN: a gas or vapour,rich in an oxidising agent such as oxygen or water vapour,used to oxidise heated semiconductor material

Definitie EN: a gaseous mixture of hydrogen and oxygen(H2/O2 mix)which is extremely flammable over a wide composition range.Oxy-hydrogen gas is created when overcharging battery systems with hydrous electrolyte
