Comparison Of Si3N4 And Other Ceramics.

The main properties for power module insulation material selection are thermal conductivity, flexural strength and fracture toughness. High thermal conductivity is essential for fast heat dissipation of power modules. Flexural strength is important for the handling and usability of ceramic substrates during packaging, while fracture toughness is key to predicting reliability.The growing need for higher reliability has recently spurred the development of ZTA (zirconia-toughened alumina) ceramics. These ceramics exhibit significantly higher flexural strength and fracture toughness. Unfortunately, the thermal conductivity of ZTA ceramics is in the same range as that of standard Al2O3, so its use is limited in high power applications with the highest power densities.The comparison shows that Si3N4 combines high thermal conductivity with high mechanical properties. A thermal conductivity of 90 W/mK can be specified and it has the highest fracture toughness (6,5 – 7 [MPa / ]) among comparative ceramics. These properties lead to the expectation that Si3N4 will exhibit the highest reliability as a metallization substrate.
