Lam Research 810-028298-009 Semiconductor substrate

Lam Research 810-028298-009 Features of Semiconductor substrates:

High purity: Semiconductor substrates are typically made of monocrystalline silicon and require extremely high purity to reduce the impact of defects and impurities on the performance of electronic components.

Flatness: The surface of the substrate must be very flat to ensure precise alignment and placement of various electronic components during the manufacturing process.

Crystal structure: Monocrystalline silicon substrates have specific crystal structures, such as Czochralski (CZ) crystals or floating zone method (FZ) crystals, which have an important impact on the performance of electronic components.

Size standardization: The size of semiconductor substrates is usually standardized to facilitate processing and transmission between different devices. Common sizes are 6 inches, 8 inches, 12 inches, etc.

Thermal stability: Semiconductor substrates need to have good thermal stability to withstand high temperatures during manufacturing.

Mechanical strength: Although the substrate is very thin (usually only a few hundred microns), they still need to have some mechanical strength to remain intact during manufacturing and handling.

Surface cleanliness: The substrate surface must be very clean to prevent the introduction of contaminants and defects during the manufacturing process.

Electrical conductivity: Although silicon itself is a semiconductor, the substrate usually needs to change its electrical conductivity through technical means such as doping to meet the needs of different electronic components.
