By Yole SystemPlus —
A SiC MOSFET power module with sintered chips for industrial applications (MD300HFR120B3S).
StarPower’s 1200V SiC MOSFET Power Module – Product Brochure – System Plus ConsultingThe market outlook for SiC devices is promising. According to Yole Développement’s CS Monitor (Q4-2021), it is expected to grow from $1B to $3.46B for the period 2021 – 2026. Nevertheless, the technical panorama of SiC devices is still diverse, and every manufacturer has its own solutions to die design and packaging integration. This leads to strong competition, which will accelerate technical innovation and lower prices. Moreover, SiC business models are still very different. We are seeing (and will continue to see) a restructuring of the supply chain driven by the main cost factors.
Since the commercialization of the first SiC device in 2001, the performance of SiC devices and the value that they add have been gradually proven. Their price has also become increasingly acceptable to end-users. StarPower, a leading power module supplier in China, provides a complete range of industry-leading power modules to customers – including SiC power modules. In this context, System Plus Consulting provides a full reverse costing study of StarPower’s 1200V SiC MOSFET Module “MD300HFR120B3S”, which targets industrial applications. This module uses sintering technology for die attach and integrates a flat baseplate.
Supported by a full teardown of the module, this report reveals StarPower’s technology choices for its assembled module as well as the designs of the different dies inside it. This report also provides insights into technology data, manufacturing cost, and the module’s selling price, as well as an estimated manufacturing cost of all the device’s parts and a selling price analysis. Included too is a physical comparison between two 1200V SiC power modules: StarPower’s MD300HFR120B3S and Rohm’s BSM180D12P3C007.
