plates made from more conventional materials, typically copper.

Copper is less expensive than the Company’s MMC solution, but its rate of thermal expansion is significantly different than that of the silicon semiconductors mounted to the baseplates. In low voltage applications, this is not a problem as the heat being generated is not enough to degrade the reliability of the power module. As voltage levels and the heat related to them go up, MMC baseplates become the preferred solution. Currently, HEV/EV manufacturers who want to save on short term costs are using power modules with copper baseplates, while those who want longer term reliability, such as those in the luxury vehicle market, may use power modules with an MMC (AlSiC) baseplate.

Of particular interest is the move to using Silicon Carbide (SiC) semiconductors instead of silicon semiconductors. SiC is more efficient than silicon allowing, among other things, for EVs and HEVs to run for longer distances on a single battery charge. This is important to CPS, as SiC semiconductors run hotter than silicon semiconductors. As such, the voltage level at which AlSiC becomes preferred over copper would be lower, creating expanded opportunities for AlSiC baseplates.

Hermetic Packages

Hermetic packaging products are primarily used for space applications such as satellites, flight applications such as avionics and undersea applications such as torpedoes, submarines and communications buoys. Hermetic packages allow the assembly of multiple semiconductor devices known as Hybrid Microelectronic Assemblies (HMA). Today’s HMA technology can, in a CPS 2”x2” package, provide the computing technology of today's typical server or yesterday's small mainframe.

CPS is the only producer of hermetic packages with AlSiC bases, combining our expertise in hermetic package production with our expertise in MMC production. The CPS AlSiC hermetic package provides tremendous benefits in terms of reduced weight and CTE matching which are extremely important for space-based programs. CPS hermetic packages are used in every current generation GPS satellite, the Mars Perseverance rover as well as many other aerospace applications.

Customers

We sell primarily to major microelectronics systems houses in the United States, Europe and Asia. Our customers typically purchase prototype and evaluation quantities of our products over a one to three year period before purchasing production volumes.

In 2024, our three largest customers accounted for 32%, 15%, and 11% of revenues, respectively.
