Looking across the IGBT manufacturing landscape, perhaps the most notable thing about the companies inhabiting it is that they are very different beasts. True, they share a common trait, elegantly combining characteristics of both MOSFETs and bipolar transistors in IGBTs that surpass both these device types across many switching applications. But different products inhabit very specific market areas, ranging from cookers and microwaves to giant municipal power transmission systems.
The specific pressures and needs of their ecological niche drive these companies to continue evolving device properties and performance. And that diversity of IGBT applications is today luring new companies, and bringing others together to boost their fortunes.

For example, Phoenix, Arizona, based ON Semiconductor had focused on IGBTs for automotive ignition, after ceasing to make motor control IGBTs in the late 1990s. But, the potential across the high performance segment of the market triggered it to release several 600V and 1,200V NGTBxx trench field stop IGBTs during 2012.
