ST Supplies SiC Tech to Semikron EV Power Modules

ST’s advanced third-generation SiC technology delivers industry-leading process stability and performance.

STMicroelectronics (ST) has declared to supply silicon carbide (SiC) technology for the eMPack electric-vehicle (EV) power modules from Semikron.

ST SiC Semikron EVThis is the result of a four-year technical collaboration between the two companies to design in ST’s advanced SiC power semiconductors for superior efficiency and industry-benchmark performance in more compact systems.

“ST’s industry-leading SiC device-manufacturing capabilities and in-depth expertise with the technology-enabled us to integrate these cutting-edge semiconductors with our advanced manufacturing processes, which enhance reliability, power density, and scalability to meet the needs of the automotive industry,” said Karl-Heinz Gaubatz, Semikron Chief Executive Officer (CEO) and Chief Technical Officer (CTO). “As we now move towards volume-production, our collaboration with ST brings the assurance of a robust supply chain that gives control over quality and delivery performance.”

“Leveraging our SiC technology, Semikron’s advanced scalable eMPack family of power modules is ready to make a major contribution towards zero-emission motoring,” said Edoardo Merli, Power Transistor Sub-Group General Manager and Executive Vice President of STMicroelectronics. “In addition to its transformative effect in e-mobility, our SiC technology, now in its third generation, is driving increased efficiency, performance, and reliability in sustainable energy and industrial power-control applications.”

SiC is quickly becoming the automotive industry’s preferred power technology for EV traction drives, contributing to greater driving range and reliability.

Semikron recently announced it had secured a billion-Euro contract to supply their innovative eMPack power modules to a major German carmaker, beginning in 2025.

Engineers from ST and Semikron cooperated to integrate the advanced STPOWER SiC MOSFETs, which control power switching in the main EV traction inverter, with Semikron’s innovative fully sintered Direct Pressed Die (DPD) assembly process.

DPD enhances module performance and reliability and enables cost-effective power and voltage scaling.

Leveraging the parameters of ST’s SiC MOSFETs, supplied as bare dice, Semikron has established 750V and 1200V eMPack platforms, addressing applications from 100kW to 750kW and battery systems from 400V to 800V.
