While most of us probably work in the volt or two range, there are many applications that require high power and/or high voltage. Examples include AC LED lighting, chargers with no-load power consumption and other power conversion and control applications. We also tend to think of geometries smaller than 90nm as being state of the art. But analog circuitry does not scale in the same way as digital circuitry, and progress has to be made in power reduction for all parts of a system. To that end X-FAB Silicon Foundries has announced XU035 a new CMOS-based process for ultra-high-voltage applications.
The new process provides low specific On-resistance 700V power devices and the lowest mask count in the foundry industry. The new process includes 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 is 13 to 18.
Besides the 700V N&PMOS, DMOS and depletion transistors with RDSon as low as 15Ohm*mm2 and 20V and 40V devices with floating high-side capabilities, XU035 can provide a wide spectrum of analog passive devices UHV resistors, MOS and MIM capacitors and protection diodes. PDKs are available for all major design environments, precise Spectre and H-Spice models, digital libraries and 2kV ESD support.
More information will be provided in a free webinar May 30 and 31, 2012.
