High Thermal Shock Si3n4 Substrate

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.

Features of Silicon Nitride wafer:

a. high temperature strength
b. superior thermal shock resistance
c. excellent wear resistance
d. good fracture toughness
e. mechanical fatigue and creep resistance
f. Excellent non-wetting property with good oxidation resistance

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;
E. The compatibility of circuit materials is good, and multi-layer wiring can be performed to achieve miniaturization of the package;
F. High thermal shock resistance, from 0 ºC to 200 ºC and then cool down, repeat 10000 times;
G. Chemical resistance, resistant oxidization, acid, alkali corrosion, service life-span up to 10 years

 

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

 

Silicon nitride is a man-made compound synthesized through several different chemical reaction methods. Parts are pressed and sintered by well-developed methods to produce a ceramic with a unique set of outstanding properties. The material is dark gray to black in color and can be polished to a very smooth reflective surface, giving parts a striking appearance. High-performance silicon nitride materials were developed for automotive engine wear parts, such as valves and cam followers, and proven effective. The cost of the ceramic parts never dropped enough to make the ceramics feasible in engines and turbochargers. The very high-quality bodies developed for these demanding high-reliability applications are available today and can be used in many severe mechanical, thermal, and wear applications.
