SiC Substrates for Advanced Packaging: Enabling High-Frequency and High-Temperature Systems

published on 27 Apr 2023

Silicon carbide (SiC) substrates for advanced packaging are rapidly becoming an important enabling technology for high-frequency and high-temperature systems. Here are some of the reasons why:


High-temperature operation: SiC substrates possess high thermal conductivity, thermal stability, and oxidation resistance, making them ideal for use in high-temperature environments. These properties enable SiC-based devices to operate at far higher temperatures than conventional silicon-based systems.


High-frequency capability: Because SiC has a very wide bandgap, from 2.2 eV to 3.4 eV depending on the crystal structure, it can support high doping concentrations and maintain high carrier mobility at high temperatures. SiC devices can operate at higher frequencies than silicon devices, and can exhibit lower loss and higher efficiency in high-frequency applications.


High-power density: SiC substrates can be used to fabricate high-power-density devices that are significantly smaller than their silicon-based counterparts. This is possible because SiC devices can handle higher power at higher temperatures, so they don't require the bulky cooling systems used in silicon devices.


Improved reliability: SiC substrates provide improved reliability because of their high mechanical strength, thermal stability, and physical hardness. This makes them ideal for harsh environments and extreme conditions.


As a result of these advantages, SiC substrates are becoming more important for advanced packaging applications in fields such as aerospace, military, and high-performance computing. Specifically, they are being used in the development of power modules, RF devices, and high-temperature sensors, among others. With demand for high-frequency and high-temperature systems continuing to grow, SiC substrates are poised to become even more important for advanced packaging in the years to come.
