Manufacturing Innovation Institute
Vision: Wide bandgap technology for a more energy efficient world
Mission: Develop a manufacturing-focused innovation ecosystem to
reduce cost, improve performance and reliability, and enable U.S.
industry dominance in WBG semiconductor devices and systems to
create jobs.
Applications
Operate above 300 oC compared to 150 oC for
Silicon-based devices
Handle 10 times
higher voltages
Produce bulbs with 10 times
more light that last 30 times
longer …
saving $250B by 2030
Reduce losses during DC-to-AC
electricity conversion by 90%
