Material Introduction:
Silicon Nitride (Si3N4) is a widely used ceramic material in high temperature application, it has high strength in both room temperature and high temperature condition, the strength of silicon nitride can be kept up to 1200ºC; the low coefficient of thermal expansion make it a ceramic material possessing excellent thermal shock resistance; at the same time, it also has good thermal conductivity.
The main features of the Si3N4 ceramic tray and substrate
A. High thermal conductivity ( up to 70 W/m.k), 3 times that of alumina ceramic substrate;
B. The thermal expansion coefficient (3.1×10-6/ºC) matches the semiconductor silicon material (3.5-4.0×10-6/ºC);
C. The bending strength is higher than that of the alumina substrate, which is twice that of the alumina substrate;
D. Excellent electrical performance, with extremely high insulation resistance and low dielectric loss;
The specification of the ceramic tray and substrate
A. The typical thickness of the silicon nitride substrate covers 0.30mm, 0.5mm, 0.635mm, 1.0mm
B. We are supplying with many round ceramic wafers, square & rectangular ceramic substrate
C. The biggest diameter of the round ceramic wafer can be up to 400mm in 3mm, 4mm, 5mm thick
D. The max. side-length of the square and rectangular ceramic substrate can be 400mm by 500mm
E. Surface treatment: it can be one-side, or double side polished to be Ra0.4 or better
