High Thermal Conductivity Aluminum Nitride Aln Ceramic Sheet Plate Board for Electronic Semiconductor

In semiconductor wafer processing, where precision, thermal uniformity and electrical insulation are non-negotiable,

our Aluminum Nitride (AlN) special-shaped parts with 170 W/(m·K) thermal conductivity stand out as the game-changing solution.

Crafted from high-purity AlN ceramic sheets, plates and boards, these custom-machined special-shaped components are engineered

to meet the rigorous demands of wafer handling, heating and cooling systems. With excellent thermal conductivity—far superior to

traditional alumina ceramics—and a thermal expansion coefficient perfectly matched to silicon, our AlN Part (special-shaped parts)

ensure rapid, uniform heat transfer, preventing wafer warpage and improving process stability. Whether it’s custom-designed wafer chucks,

heater blocks or thermal shields, these components deliver reliable performance in CVD, etch and deposition processes,

empowering your semiconductor manufacturing lines to achieve higher yields and efficiency.

Application 
Aluminum Nitride Part Application:
Here are the common purity levels of aluminum nitride powder (AlN) and their typical applications:
1. Industrial Grade Purity•Purity Range: 95% - 98%•Applications: Generally used in applications where high purity is not critical, such as basic ceramic

materials and composites.
2. High Purity•Purity Range: 99% - 99.5%•Applications: Suitable for most electronic packaging and thermal management applications, as well as

high-performance ceramic materials.
3. Ultra-High Purity•Purity Range: 99.5% - 99.99%•Applications: Used in advanced electronic packaging, LED packaging, and high-performance catalyst

supports where extremely high purity is required.
4. Special Purity•Purity Range: >99.99%•Applications: Used in specific scientific research and high-precision technology applications, such as

aerospace and military fields.
Selection Recommendations•Choose Based on Application Requirements: Different applications have different purity requirements. Selecting the appropriate purity can balance performance and cost.
