Question

Which is the most striking feature in monolithic integrated circuit transistor?

(a) Collector contact is present at the bottom of IC

(b) Collector contact is present at the top of IC

(c) Collector contact is absent

(d) Collector contact is present on one of the sides of IC

This question was addressed to me by my school teacher while I was bunking the class.

This intriguing question originated from Active and Passive Components of IC topic in portion IC Fabrication of Linear Integrated Circuits

Answer 1

Correct option is (b) Collector contact is present at the top of IC

Navigate through clarity with: In IC transistor, the collector contact has to be taken from the top because collector is isolated from the substrate and next isolation island by reverse biased diodes.
