IC Chip which integrates all the electronic components on a single chip is made up of which semiconductor?

An integrated circuit or monolithic integrated circuit also referred to as an IC chip is a set of electronic circuits on one small flat piece of semiconductor material that is normally silicon. The integration of large numbers of tiny transistors into a small chip results in circuits that are orders of magnitude smaller, faster, and less expensive than those constructed of discrete electronic components. ICs are now used in virtually all electronic equipment and have revolutionized the world of electronics.
