January 24, 2022 By WatElectronics

This article lists 100 Semiconductor Device MCQs for engineering students. All the Semiconductor Device Questions and Answers given below include a hint and a link wherever possible to the relevant topic. This is helpful for users who are preparing for their exams, interviews, or professionals who would like to brush up their fundamentals on Semiconductor devices.

A device that relies on the properties of a semiconductor and functions accordingly is called a semiconductor device. Semiconductor devices such as diodes, rectifiers, amplifiers, etc are designed using semiconductor substances that include gallium, silicon, and germanium.

These devices are designed to overcome the drawback attained by vacuum tubes. These devices can be manufactured on 2 platforms is on an integrated chip called IC and as single discrete devices. The conductivity of these devices mainly depends on the level of doping impurities such as p-type or n-type.

These semiconductor devices are classified into 2 types namely majority carrier devices and minority carrier devices. Where majority carrier device includes JFET, Schottky diode and powers MOSFET and BJT, PIN diode, IGBT and thyristor are the examples of minority carrier devices.

These devices benefit in terms of minim required voltage, compact, budget-friendly, small size, and more life span. But lack in terms of noise level, miss handling of high power and high frequency. Multivibrators, Schottky diode, TRIAC, BJT, and more are a few of the applications of semiconductor devices.
