BCD: a key technology for power integrated circuits.

ST invented the BCD (Bipolar-CMOS-DMOS) technology - revolutionary at the time - in the mid-eighties and has continually developed it ever since. BCD is a family of silicon processes, each of which combines the strengths of three different process technologies onto a single chip.

Analog Bipolar

The best for analog functions.

Digital CMOS

The best for digital processing.

Power DMOS

For power and high voltage elements.

The best of the 3 worlds

This combination of technologies brings many advantages: improved reliability, reduced electromagnetic interference and smaller chip area.

BCD has been widely adopted and continuously improved to address a broad range of products and applications in the fields of power management, analog data acquisition and power actuators.


A recognized innovation

In May 2021, BCD was honored with the prestigious IEEE milestone for ST’s historical “Multiple Silicon Technologies on a Chip” achievement. The IEEE Milestones in Electrical Engineering and Computing program honors significant technical achievements in all areas associated with IEEE.

Milestones recognize the technological innovation and excellence for the benefit of humanity found in unique products, services, seminal papers, and patents.
