Product Introduction

alumina ceramic sheet substrate with groove


Our alumina substrate has well-balanced properties of insulation, thermal conductivity and breaking strength. Moreover, one of the unique properties is its surface roughness. We can provide the ceramic substrate which is excellent in adhesion with a thin film and thick film metalization due to fine particles.


Good smoothness / flatness with less porosity. Excellent in adhesion with thin film and thick film materials.

Less variance in outline, plate thickness, slit pitch, etc.

Minimal warpage, bending, and undulation.

Physical and chemical properties are stable even under a hot environment. Excellent in thermal shock resistance. High thermal conductivity and coefficient of thermal expansion similar to that of silicon.

Superior mechanical strength. Products with higher mechanical strength are also in our lineup.

Excellent resistance against oil and chemical.

Excellent in insulation properties, high dielectric breakdown voltage, high surface resistivity / volume resistivity, and small dielectric constant.

Stable breaking strength, and less variance in shape or dimensions.

The high reflective substrate, especially suitable for optical applications such as LED, is also available.
