Description of the Si wafer

Silicon wafers are thin, flat disks made from highly purified single-crystal silicon and are widely used in the semiconductor industry.

These wafers are the basic substrate for manufacturing integrated circuits and a variety of electronic devices.

Silicon wafers typically range from 2 inches (50 mm) to 12 inches (300 mm) in diameter, and their thickness varies depending on size, typically between 200 µm and 775 µm.

Silicon wafers are manufactured using the Czochralski or Float-Zone methods and are carefully polished to obtain a mirror surface with minimal roughness. They can be doped with elements such as boron (P-type) or phosphorus (N-type) to modify their electrical properties.

Key properties include high thermal conductivity, low coefficient of thermal expansion, and excellent mechanical strength.

Wafers can also have epitaxial layers or thin silicon dioxide layers to enhance electrical properties and insulation.

They are processed and handled in a cleanroom environment to maintain purity, ensuring high yield and reliability in semiconductor manufacturing.

FAQ

1. Q: What difference between P-type and N-type of Si wafers?

A: P-type silicon wafers have holes as the main charge carriers, while N-type wafers have electrons, with minimal differences in other physical properties like resistivity.

2. Q: Si wafer, SiO2 wafer and SiC wafer, what are the main differences of them?

A: Silicon (Si) wafers are pure silicon substrates used primarily in semiconductor devices,

SiO₂ wafers have a silicon dioxide layer on the surface, often used as an insulating layer.

Silicon carbide (SiC) wafers are composed of a compound of silicon and carbon, offering higher thermal conductivity and durability, making them suitable for high-power and high-temperature applications.
