Silicon wafer
A silicon wafer is a thin, circular slice of single-crystal semiconductor material used in manufacturing of semiconductor devices and integrated circuits.
Industry: Semiconductors

Silicon wafer
p-type semiconductor
Semiconductors; Silicon wafer
Semiconductor in which the concentration of holes is much higher than the concentration of electrons (n>>p); holes are majority carriers and dominate conductivity.
primary flat
Semiconductors; Silicon wafer
The flat of longest length on the wafer, oriented such that the chord is parallel with a specified low index crystal plane; major flat.
poly crystalline material
Semiconductors; Silicon wafer
Many (often) small single-crystal regions are randomly connected to form a solid; size of regions varies depending on the material and the method of its formation. Heavily-doped poly Si is commonly ...
polishing
Semiconductors; Silicon wafer
Process applied to either reduce roughness of the wafer surface or to remove excess material from the surface; typically polishing is a mechanical-chemical process using a chemically reactive slurry.
point defect
Semiconductors; Silicon wafer
A localized crystal defect such as lattice vacancy,interstitial atom, or substitutional impurity. Contrast with light point defect.
particle
Semiconductors; Silicon wafer
A small,discrete piece of foreign material or silicon not connected crystallography to the wafer.
planar defect
Semiconductors; Silicon wafer
Also known as area defect; basically an array of dislocations, e.g. Grain boundaries,stacking faults.
