Semiconductor Device

* The Semiconductor device, electronic circuit is made up of a material that is neither a good conductor nor a good insulator.

* Semiconductor devices are nothing but electronic components that exploit the electronic properties of semiconductor materials, like as silicon, germanium, and gallium arsenide, as well as organic semiconductors.
