Semiconductor devices are electronic components that exploit the electronic properties of semiconductor materials. These materials include silicon, germanium, and gallium arsenide, in addition to organic semiconductors.
These devices have replaced vacuum tubes in a lot of applications. They make use of electronic conduction in the solid-state rather than the thermionic emission in a high vacuum.
These devices are manufactured for both discrete devices and integrated circuits, which comprise of a few to billions of devices manufactured and interconnected on a single semiconductor substrate or wafer.
Moreover, a semiconductor material is a device that allows the passage of electric current through it. Let’s take the device CPU as an example. It comprises of many numbers of transistors within it.
Similarly, these transistors comprise the semiconductor material which allows the passage of current and a switch controls all this. In the transistor, the passage of electric current is controlled by the actions on the basis of the state of the switch whether it is on or off.
Thus, such a device, which allows the current to pass through them partially, we refer to it as a Semiconductor Device.
Semiconductors form an integral part of modern automobiles. A typical vehicle may have up to 100 electronic control units (ECU’s) embedded in systems which include those governing engine, transmission, active safety, passenger comfort and infotainment.
