Which of the following is most difficult to fabricate in an IC ?
Correct answer: D. Capacitor
- A. Diode
- B. Transistor
- C. FET
- D. Capacitor
Explanation
Capacitors are most difficult to fabricate in an IC because useful capacitance requires relatively large chip area and carefully formed insulating layers. Diodes and transistors can be made directly from semiconductor junctions using standard IC processes.
