Alumina substrate (ceramic substrate) with excellent adhesion to thick and thin film materials.
Alumina substrates (ceramic substrates) with minimal dimensional variation in shape and thickness, small warping, bending, and waviness, possessing stable quality and excellent characteristics.
MARUWA Corporation can develop semiconductor ceramic substrates from raw materials, allowing us to meet a wide variety of requests from upstream to downstream processes, including plain substrates, laminations, and circuit formation. Our alumina substrates (ceramic substrates) have a low porosity due to fine particles, providing an excellent surface condition in terms of smoothness and flatness, as well as superior adhesion to thick and thin film materials. They exhibit minimal dimensional variation in shape and thickness, with low warping, bending, and waviness. Their physical and chemical properties remain stable even in high-temperature environments, and they excel in thermal shock resistance. Additionally, they have a thermal expansion coefficient close to that of silicon and possess high thermal conductivity. 【Features】 ■ Excellent mechanical strength, with high-strength substrates available for increased durability ■ Outstanding oil and chemical resistance ■ High dielectric breakdown voltage, surface resistance, and volume resistance, with a low dielectric constant ■ High reflectivity substrates suitable for LED applications are also available.
