BCDMOS
Chip manufacturing technology
BCDMOS is a complex circuit composed of bipolar, CMOS and DMOS devices.
BCDMOS technology allows to drive discrete high voltage components (several hundred of operating voltage) at high frequency while keeping high integration with technology nodes down to 40 nm or 22 nm. Many applications still use process node of 0.35μm in 2023.
Application of this type of circuits are found in automotive, audio amplifier, RF, industry, silicon photomultiplier (SiPM).
History
SGS (now STmicroelectronics) invented the BCD (bipolar-CMOS-DMOS) technology - revolutionary at the time - in 1985 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.
Features
According to Maxim website, it is an innovative process characteristics that provides the following features:
high break-down voltage but small transistors,
quite low on-resistance, which is important for the integration of multiple power FETs of low resistivity,
double-metal-layer to support hi-current
combining thin film and poly-poly caps (in silicon). High-accuracy references can be integrated.
According to Dongbu HiTek's news, it claims to launch the first 0.18-micrometre BCDMOS process in industry. The new process integrates logic, analog and hi-voltage functions to reduce size.
The public source identifies “BCDMOS” as chip manufacturing technology. This brief keeps that definition visible, then builds a research path around BCDMOS, Chip and manufacturing.
Why this record matters
A short description can identify a subject without explaining its stakes. For “BCDMOS”, the useful work is to connect “chip manufacturing technology” to the records capable of establishing context and consequence.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Apr 20, 2026. The linked authority identifier is Q4835153. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2023 and 1985.
A general summary may omit uncertainty, sample limits or methodological disagreement that is explicit in the technical record. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
Check terminology, classification and the date of the cited evidence. Scientific names and technical consensus can change while older records retain historical value.
- Current terminology
- Classification context
- Finding cited technical literature
Primary datasets, specimen catalogues, standards bodies and the most recent peer-reviewed literature.
Three-step research path
- Establish the record: confirm the title “BCDMOS”, its source revision and the description used here.
- Expand the search: follow BCDMOS primary sources, BCDMOS archive and BCDMOS research across catalogues and specialist indexes.
- Test the account: compare the strongest cited source with the responsible institution’s current record and note any disagreement.
