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

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

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"

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

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

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

michigan0 Sang Kim First, 28nm bulk is in volume manufacturing for several years by the major semiconductor companies but not 28nm FDSOI today yet. Why not? Simply because unlike 28nm bulk the LDD(Lightly Doped Drain) to minimize hot carrier generation can't be implemented in 28nm FDSOI. Furthermore, hot carrier reliability becomes worse with scaling, That is the major reason why 28nm FDSOI is not manufacturable today and will not be. Second, how can you suppress the leakage currents from such ultra short 7nm due to the short channel effects? How thin SOI thickness is required to prevent punch-through of un-dopped 7nm FDSOI? Possibly less than 4nm. Depositing such an ultra thin film less then 4nm filum uniformly and reliably over 12" wafers at the manufacturing line is extremely difficult or not even manufacturable. If not manufacturable, the 7nm FDSOI debate is over!Third, what happens when hot carriers are generated near the drain at normal operation of 7nm FDSOI? Electrons go to the positively biased drain with no harm but where the holes to go? The holes can't go to the substrate because of the thin BOX layer. Some holes may become trapped at the BOX layer causing Vt shift. However, the vast majority of holes drift through the the un-dopped SOI channel toward the N+Source,...
