Company Profile
Product Details
alumina wafers for thin film circuits,alumina wafers for semiconductor processing,sensor component substrates
We are able to manufacture alumina wafers up to a maximum size of φ300mm (φ12 inch).
With a high density and few pores, it is possible to form fine
circuit patterns.
We also handle substrates with fine rounded/square holes or slits,
as well as polished substrates.
Main Applications
- A.Alumina Substrates for thin film circuits
- B.Sensor component substrates
- C.Substrates for semiconductor processing
Features
- Able to manufacture up to a maximum size of φ300 mm (φ12 inch).
- The material has a low surface roughness (Ra 0.02μm or less) and few surface pores which makes it possible to form fine circuit patterns.
- The high bending strength allows a reduced thickness.
- The small dielectric loss tangent in the high frequency band makes it ideal for use with high-frequency circuits.
