Pure silicon wafers Pure silicon boules of 300 mm diameter and 30 ft long, can weigh up to 400 Kg. These boules are sliced into thin disks (wafers) using diamond saws. Standard sizes of wafers are: 100 mm (4”) diameter x 500 µm thick.150 mm (6”) diameter x 750 µm thick.
Silicon Semiconductor | Electrical4U
The silicon with added impurities can become N-type semiconductor or P-type semiconductor.If the impurity with five valence electrons donor (Nitrogen-N, Phosphorus-P, Arsenic-As, Antimony-Sb, Bismuth- Bi) is added to the pure tetravalent silicon, the four impurity
Chemical vapor deposition - Wikipedia
Chemical vapor deposition (CVD) is a vacuum deposition method used to produce high quality, high-performance, solid materials. The process is often used in the semiconductor industry to produce thin films.In typical CVD, the wafer (substrate) is exposed to one or more volatile precursors, which react and/or decompose on the substrate surface to produce the desired deposit.
Silicon Carbide (SiC) | Morgan Technical Ceramics
Sintered SiC is produced from pure SiC powder with non-oxide sintering aids. Conventional ceramic forming processes are used and the material is sintered in an inert atmosphere at temperatures up to 2000ºC or higher. Both forms of silicon carbide (SiC) are
