The main features of Si3N4 ceramic wafers and substrate1. 1.High thermal conductivity ( up to 70 W/m.k), 3 times that of alumina ceramic substrate;
2. The thermal expansion coefficient (3.1×10-6/ºC) matches the semiconductor silicon material (3.5-4.0×10-6/ºC);
3. The bending strength is higher than that of the alumina substrate, which is twice that of the alumina substrate;
4. Excellent electrical performance, with extremely high insulation resistance and low dielectric loss;
5. The compatibility of circuit materials is good, and multi-layer wiring can be performed to achieve miniaturization of the package;
6. High thermal shock resistance, from 0 ºC to 200 ºC and then cool down, repeat 10000 times;
7. Chemical resistance, resistant oxidization, acid, alkali corrosion, service life-span up to 10 years
