Ceramic Semiconductor valve Pad Mechanical strength High temperature resistance Al2O3 Ceramic Parts
As a precision Semiconductor valve manufacturer, we produce and sales multi types ceramic products for Semiconductor as our customer requirements.
We can offer alumina ceramics products with different proportions(95%-99.98% Al2O3).
Alumina ceramics have a excellent properties for chemical and physical stability.
Thermal properties: High heat resistance and high thermal conductivity...
Mechanical properties: High strength and high hardness
We offer a wide range of ceramic products for the Semiconductor Industry including:
Windows
Wafer chucks and arm
Focus rings
Gas distribution plates
Cover rings
Insulators
Liners & process tubes
Nozzles
Domes
Air bearings
Our ultra-flat ceramic vacuum wafer chucks improve yield management for semiconductor wafer processing. Low-surface-contact configurations minimize risk of back-side particles negatively affecting wafer geometry for precision applications.
Our materials offer:
Dimensional stability
Corrosion resistance
Mechanical strength
Electrical insulation
High temperature resistance
