Silicon wafer

Chuck mark

Semiconductors; Silicon wafer

Any physical mark on either surface of a wafer caused by robotic end effector, chuck, or wand.

Crystal

Semiconductors; Silicon wafer

Solid featuring periodic spatial arrangement of atoms throughout the entire piece of material.

Enclosed ultra-clean space necessary for semiconductor manufacturing. Airborne particles are removed from the space to specified minimum levels, room temperature and humidity are strictly controlled; ...

Wafer diameter

Semiconductors; Silicon wafer

The linear distance across the surface of a circular slice which contains the slice centre and excludes any flats or other peripheral fiduciary areas. Standard silicon wafer diameters are: 25. 4mm ...

Wafer bonding

Semiconductors; Silicon wafer

Process in which two semiconductor wafers are bonded to form a single substrate; commonly applied to form SOI substrates; bonding of wafers of different materials, e.g. Gaas on Si, or sic on Si; is ...

Wafer

Semiconductors; Silicon wafer

Thin (thickness depends on wafer diameter, but is typically less than 1mm),circular slice of single-crystal semiconductor material cut from the ingot of single crystal semiconductor; used in ...

Total thickness cariation (TTV)

Semiconductors; Silicon wafer

The maximum variation in the wafer thickness. Total Thickness Variation is generally determined by measuring the wafer in 5 locations of a cross pattern (not too close to the wafer edge) and ...
