AI Technical Summary
Existing ceramic substrates used in electronic devices often suffer from insufficient smoothness of the support surface, leading to potential electrostatic discharge (ESD) issues and impaired thermal conductivity due to the formation of irregularities during sintering.
A ceramic substrate is manufactured with a base material containing a sintered body of ceramic particles, covered by a coating of sintered α-alumina particles with a smaller average diameter, which fills in irregularities and provides a smooth, high thermal conductivity surface.
The substrate achieves improved thermal conductivity and ESD resistance by ensuring a smooth surface for electronic components, reducing the likelihood of electrostatic discharge and enhancing the reliability of electronic devices.
