Silicon wafer

Physical vapour deposition (PVD)

Semiconductors; Silicon wafer

Deposition of thin film occurs through physical transfer of material (e.g. Thermal evaporation and sputtering) from the source to the substrate; the chemical composition of deposited material is not ...

Oxygen in silicon

Semiconductors; Silicon wafer

Oxygen finds its way into silicon during the Czochralski single-crystal growth process; in moderate concentration (below 1017cm3) oxygen improves mechanical properties of a silicon wafer;excess ...

Nanometer, nm

Semiconductors; Silicon wafer

Unit of length commonly used in semiconductor industry; one billionth of a meter, 10-9m (nm); terms such as microchip and micro technology are being replaced with nanochip and nanotechnology.

Notch

Semiconductors; Silicon wafer

An intentionally fabricated indent of specified shape and dimensions oriented such that the diameter passing through the centre of the notch is parallel with a specified low index crystal direction.

N-type semiconductor

Semiconductors; Silicon wafer

Semiconductor in which the concentration of electrons is much higher than the concentration of holes (p>>n); electrons are majority carriers and dominate conductivity.

Localised light-scatter

Semiconductors; Silicon wafer

An isolated feature, such as particle or pit, on or in a wafer surface, resulting in increased light scattering intensity relative to that of the surrounding wafer surface; sometimes called a light ...

Haze

Semiconductors; Silicon wafer

Non-localized light scattering resulting from the surface topography (micro roughness) or from dense concentrations of surface or near-surface imperfections.
