What is the Function of Focus Rings?

Focus rings are the essential components to ensure the uniformity and stability of the semiconductor etching processes. Through precise control of electric and thermal fields, focus rings can concentrate plasma on the wafer surface, ensuring consistent etching results across all locations on the waf......

SiC Ceramic Mechanical Seals

Silicon carbide has good chemical stability and can withstand various highly corrosive acidic and alkaline media, making it suitable for mechanical seals in corrosive media. Corrosive wear is a major form of failure for friction pair materials. Hot-pressed sintered silicon carbide forms a protective......

What is the particle defects?

Particle defects refer to the tiny particulate inclusions inside or on the semiconductor wafers. They can damage the structural integrity of semiconductor devices and cause electrical faults such as short circuits and open circuits. Since these problems caused by particle defects can seriously af......

Why have vertical furnaces become the mainstream choice？

Vertical furnaces are the vertically placed high-temperature heating devices specially designed for the heat treatment of semiconductor manufacturing. The complete vertical furnace system is composed of the high-temperature resistant furnace tube, the heating element, the temperature control system,......

How to Choose the Right Rigid Felt for Soundproofing and Acoustic Panels

The core of a great acoustic treatment often lies in a specialized material: Rigid Felt. Not all felts are created equal, and selecting the right one is crucial for performance and durability.

High-purity Fused Quartz Crucible for Single-crystal Pulling

Currently, monocrystalline silicon is produced using polycrystalline silicon as a raw material and the Czochralski method. In monocrystalline silicon production, the quartz crucible is a critical material for melting silicon and crystal growth, and it has a direct and significant impact on the produ......
