There is another event - related to above.
Why is Power Integrations not announcing the Velox acquisition? PI now has a GaN-on-silicon fab facility.
Velox revenues were about $2.4M with 18 employees (most probably out of $$$).
It means that PI is very aggressive in investments for wide bandgap semiconductors (both SiC and GaN). STM has apparently made a pass on the fab and most probably acquired technology know-how for its internal developments.
GaN on silicon technology will likely change the landscape of Power Mngmt ICs - togheter with Digital power control it will allow major breakthroughs in power reduction and miniaturization.
Great achievement by the Toyohashi University of Technology researchers, this has got the benefits as listed in the article but simultaneously one more advantage will be that the embedded circuits will be easily tested due to the on chip LEDs as an indicating elements.
