Question

Which among the following is not easy to fabricate on an Integrated Circuit?

(a) Inductor

(b) Resistor

(c) Capacitor

(d) Transistor

This question was posed to me in an interview.

My question is from Semiconductor Electronics in section Semiconductor Electronics : Materials, Devices and Simple Circuits of Physics – Class 12

Answer 1

Right answer is (c) Capacitor

The best I can explain: Capacitors are not easy to fabricate on an Integrated Circuit. In fact, they are the most difficult ones to fabricate. This is because capacitors require a lot of attributes such as electromagnetic compatibility, microfabrication techniques, new magnetic materials, etc. and to integrate them, it costs a lot. Therefore, fabricating capacitors is a challenging task.
