BCD
Bipolar-CMOS-DMOS
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.
Multiple Silicon Technologies on a Chip, 1985
Agrate Brianza, Italy, Dedicated 18 May 2021 - IEEE Italy SectionSGS (now STMicroelectronics) pioneered the super-integrated silicon-gate process combining Bipolar, CMOS, and DMOS (BCD) transistors in single chips for complex, power-demanding applications. The first BCD super-integrated circuit, named L6202, was capable of controlling up to 60V-5A at 300 kHz. Subsequent automotive, computer, and industrial applications extensively adopted this process technology, which enabled chip designers flexibly and reliably to combine power, analog, and digital signal processing.
