Silicon wafer

Slurry

Semiconductors; Silicon wafer

A liquid containing suspended abrasive component; used for lapping, polishing and grinding of solid surfaces; can be chemically active; key element of CMP processes.

Silicon-on-sapphire (SOS)

Semiconductors; Silicon wafer

Special case of SOI where an active Si layer is formed on top of a sapphire substrate (an insulator)by means of epitaxial deposition; due to a slight lattice mismatch between Si and sapphire, Si ...

Slice orientation

Semiconductors; Silicon wafer

The angle between the surface of a slice and the growth plane of the crystal. The most common slice orientations are , and .

Silicon-on-insulator (SOI)

Semiconductors; Silicon wafer

Silicon substrate of choice in future generation CMOS ics; basically a silicon wafer with a thin layer of oxide (sio2) buried in it; devices are built into a layer of silicon on top of the buried ...

Process used to fabricate bonded SOI substrates by cleaving the top wafer close to the desired thickness of the active layer. Before bonding, one wafer is implanted with hydrogen to a depth that will ...

Test grade

Semiconductors; Silicon wafer

A virgin silicon wafer of lower quality than Prime, and used primarily for testing processes. SEMI indicates the bulk, surface, and physical properties required to label silicon wafers as "Test ...

Target

Semiconductors; Silicon wafer

Source material used during evaporation or deposition; in sputtering, typically in the form of high purity disc; in e-Beam evaporation, typically in the form of a crucible. In thermal evaporation, ...
