New Product: High-Purity Alumina Substrates (99.5% Alumina)
The Functional Ceramics Product Division has introduced High-Purity Alumina Substrates (99.5% Alumina) to its product lineup. These new substrates offer excellent surface smoothness, making them ideal for fine circuit patterns and thin-film circuit applications.
Features
- High purity (99.5% or higher) with low internal porosity for stable electrical properties
- Excellent surface smoothness improves the yield of fine-pattern fabrication
- High flexural strength provides excellent handling characteristics, even with thin substrates
- High insulation and low dielectric loss ensure stable performance in high-voltage, high-frequency, and plasma environments
Behind the Development
As electronic devices continue to become smaller and more sophisticated, demand has grown for alumina substrates with higher purity and more stable performance, particularly for thin-film applications and fine line/space (L/S) designs.
In response to customer requests for a reliable supply of high-purity alumina substrates and the market’s increasing demand for advanced ceramic materials, NIKKO collaborated with a partner company to develop a new high-purity alumina grade by combining each company’s technological strengths.
Utilizing its expertise in ceramic manufacturing, from raw material formulation to forming and sintering, NIKKO optimized the material properties required for thin-film applications and integrated them into the production process.
The result is a 99.5% Alumina Substrate that delivers excellent performance for thin-film circuits and fine-pattern applications.
Future Applications
In addition to outstanding surface smoothness, the 99.5% Alumina Substrate offers excellent electrical insulation, high heat resistance, and superior mechanical strength. It is well suited for use as an insulating heat-dissipation substrate in semiconductors, automotive electronics, and a wide range of electronic devices, providing reliable performance even in demanding operating environments.
