Silicon wafer
Bipolar
Semiconductors; Silicon wafer
Semiconductor device fabrication technology which produces transistors that use both holes and electrons as charge carriers.
Acceptor
Semiconductors; Silicon wafer
An impurity in a semiconductor which accepts electrons excited from the valence band, leading to hole conduction.
Active Si layer
Semiconductors; Silicon wafer
Silicon layer on top of the buried oxide (BOX) in SOI substrates.
Czochralski crystal growth
Semiconductors; Silicon wafer
Process utilising crystal pulling to obtain single-crystal solids; the most common method for obtaining large diameter semiconductor wafers (e.g. 300mm Si wafers); desired conductivity type and ...
Crystal pulling
Semiconductors; Silicon wafer
Process in which single-crystal seed is slowly withdrawn from the melt and material condenses at the liquid-solid interface gradually forming a rod-shaped piece of single-crystal material. Crystal ...
Bow
Semiconductors; Silicon wafer
Concavity, curvature, or deformation of the wafer centerline independent of any thickness variation present.
Chemical mechanical polishing (CMP)
Semiconductors; Silicon wafer
A process for removal of surface material from the wafer which uses chemical and mechanical actions to achieve a mirror-like surface for subsequent processing.
