LED news and insight from our technology editor Steve Bush, who has been messing with LED lighting for more years than he would care to remember.
X-Fab adds 700V CMOS process to support LED lighting
X-Fab, the silicon foundry, has added a 700V CMOS process for ultra-high-voltage consumer applications such as AC LED lighting, chargers with no-load power consumption and other power conversion and control applications, writes David Manners.
“Our new XU035 process enables our customers to compete effectively in energy-efficiency applications like LED lighting and phone chargers that require ultra-low standby power,” says X-Fab’s Voker herbig.
The process provides low specific On-resistance 700V power devices and the lowest mask count in the foundry industry, says X-Fab.
The process includes cost-efficiency features such as a single poly and single 5V gate oxide architecture, 8-inch bulk starting material, optional third routing and power metals and optional MIM capacitors. It also includes a depletion transistor and a high-resistive poly module. Depending on the process module combination chosen, the total mask count range of 13 to 18 is the foundry industry’s lowest.
