I need a semiconductor process who can support 500V above to design my own H-Bridge on Chip.
Heat dissipation has to be good.

thanks
 

I need a high volume foundry, not Dalsa, Dalsa is low volume. TSMC? ON-Semi? Austria Semi? or IBM? anyone know Japanese foundry?
 

Dalsa make over 100,000 wafers per annum. How many do you need?

The main fabs tend to concentrate on processes for consumer products, displays and automotive which don't often require more than 40V or so. If you want 500V you need to look away from the mainstream.

I used Dalsa before, the process is not good at all, not reliable!
 

how about vanguard?

taiwan fab
 

Hi,

As i know, UMC has a 700V CDMOS process.
