Wafer Foundry Offers Advanced BCD PROCESS

Jazz Semiconductor, an independent wafer foundry focused primarily on specialty CMOS process technologies, has announced the availability of its 0.25-micron bipolar CMOS DMOS (BCD25) processes targeting the power management and high-voltage markets. The Jazz 0.25-micron offering provides a migration path from its 0.5-micron, 40-V BCD process.

Jazz BCD25 can provide significant cost reductions by allowing designers of power devices to achieve a shrink of up to 50% in device area size as compared to BCD05. Jazz BCD25 processes offer advanced CMOS, a combination of bipolar NPN and PNP devices, as well as high-voltage LDMOS FETs that take advantage of 0.25-micron rules to reduce on-resistance and size of power cells used in complex power management chips.

The Jazz BCD25 process features 5-V CMOS with a future option for dual-gate 3.3-V/5-V CMOS, a 1-kΩ poly resistor, MIM capacitors, a broad voltage range of LDMOS transistors that is designed to operate at 12 V, 20 V and 40 V with ultra-low RDS(ON) at all voltage levels, VIA stacking, thick top power metal (3 µm) for improved current-carrying capacity, ESD protection circuits, and triple well isolation. BCD25 reuses existing high-performance and high-density features from Jazz Semiconductor’s existing 0.35-micron and 0.25-micron processes.

Jazz Semiconductor offers a full design kit and modeling support for the BCD25 process including support for digital standard cells and analog models for all devices. The design kit also includes a novel scalable model for the LDMOS devices that allows designers to vary the voltage rating and RDS(ON) of the high-voltage LDMOS devices continuously from 20 V to 40 V rather than making use of fixed cells as typically done in the past.
