$35M investment in GaN technology is substantial...I thought GaN was a fairly small niche market (less than $100M in revenue annually)

How much GaN does $35M buy these days? A few dozen wafers?

Thank you for the encouraging news. What type of products (devices and/or modules) are considered by this investment…..and in which timeframe? Re Transphorm and 600V devices - are these transistors or diodes? Transistors may be MUCH more difficult to make. Also are the 600V devices really GaN-on-Silicon or perhaps, as an intermittent step, SiC? Many thanks

Iniewski - these are Power GaN transistors, that is, not RF GaN devices (Eudyna/Fujitsu) - potentially a much bigger market with intense commercialization activities by compamies and countries worldwide. There is a race to solve (to a degree) the intrinsic phenomena known as the "current collapse"

Here is a link to a recent announcement by Transphorm about this. They are the first to attain JEDEC qualification for 600V transistor devices: http://bit.ly/PXKb5s

thank you @sranje for clarification...what is the "current collapse" phenomena? thermal runaway?
