Ceramic for semiconductor, liquid crystal manufacturing machines, and for solar equipment

Advanced Ceramic products for semiconductor, liquid crystal manufacturing machines, and for solar equipment

Manufacturing machines of semiconductors required material with high rigidity, processing accuracy, seismic capacity, heat resistance, heat conductivity efficiency, surface processing accuracy, metal contamination, chemical resistance, gas resistance, plasma resistance,excellence insulation performance, electric permittivity, dielectric loss tangent, volume resistivity, low dust generation (particles), cost, etc.
Ceramic Parts Hong Kong propose that with the application of highly-pure Alumina (Al₂O₃ purity 99.5% to 99.99%), Aluminum Nitride (ALN), and Yttria (Y₂0₃), we can satisfy the requirements above.

NPC’s ceramic manufacturing policy is producing high-density ceramic with tiny crystal composition. This policy match with the requirement from the semiconductor device industry because Ceramic Parts Hong Kong low pore vacancy ceramics is suitable for plasma generation device.

Non-metal contamination grade Alumina is also widely used for front end semiconductor manufacturing.

Because of its features, those materials are used as:

-Domes
-Focus rings,
-Etching nozzles, Shield
-Shower head
-Chamber Liner
-Cover Ring
-Target machine
-Heater material
-Wafer table
-RF window
-Lifter Pin
-End effector/arm
-Deposition Ring
and so on.

Aluminum nitride(AlN) is excellent in heat conductivity, as an electrical insulation, heat radiation resistance and heat shock resistance. Furthermore, it has thermal expansion coefficient is similar to a silicon wafer.
Yttria is the material that has excellent plasma resistance.

All kinds of material/items are possible to order with customized design and small quantity.
