Advantages of Semicorex Al2O3 Vacuum Chuck

1. Uniform Micro-Porous Ceramic Technology

The Al2O3 Vacuum Chuck is constructed using micro-porous ceramic technology, which involves the use of uniformly sized nano-powders. This technology ensures that the pores are evenly distributed and interconnected, resulting in high porosity and a uniformly dense structure. This uniformity enhances the vacuum chuck’ s performance, providing consistent and reliable wafer support.

2. Exceptional Material Properties

The ultra-pure 99.99% Alumina (Al2O3) used in the Al2O3 Vacuum Chuck offers a range of exceptional properties:

Thermal Properties: With high heat resistance and excellent thermal conductivity, the Al2O3 Vacuum Chuck can withstand the high temperatures commonly encountered in semiconductor manufacturing.

Mechanical Properties: The high strength and hardness of Alumina ensure that the Al2O3 Vacuum Chuck is durable and resistant to wear and tear, providing long-lasting performance.

Other Properties: Alumina also offers high electrical insulation and corrosion resistance, making the Al2O3 Vacuum Chuck suitable for a wide range of manufacturing environments.

3. Superior Flatness and Parallelism

One of the key advantages of the Al2O3 Vacuum Chuck is its high flatness and parallelism. These properties are crucial for ensuring precise and stable wafer handling, minimizing the risk of damage and ensuring consistent processing results. Additionally, the good air permeability and uniform adsorption force of the Al2O3 Vacuum Chuck ensure smooth and reliable operation.
