Substrate
Collector
Emitter
None of the mentioned
Answer is Right!
Answer is Wrong!
The correct answer is: A. Substrate
A substrate is a semiconductor material upon which other semiconductor devices are built. In BiCMOS, the n-well is created for the bipolar transistor and is used as the substrate. The n-well is a region of n-type semiconductor material that is surrounded by p-type semiconductor material. The n-well provides a low-resistance path for current to flow from the collector to the emitter of the bipolar transistor.
The other options are incorrect because:
- The collector is the region of the bipolar transistor that receives current from the emitter.
- The emitter is the region of the bipolar transistor that injects current into the base.
- None of the mentioned is not a valid option.
