The Brains of Modern Electronics
A Semiconductor is a substance with electrical properties that fall between those of a conductor, such as copper, and an insulator, such as glass. This means that semiconductors can control the flow of electricity, which is necessary for many electrical devices.
Semiconductors are made of materials such as silicon, germanium, and gallium arsenide. These materials undergo purification and then doped with impurities to make various types of semiconductors. A phosphorus-doped semiconductor, for example, will contain more electrons than a boron-doped semiconductor. This variation in electron concentration results in a voltage difference that can be utilized to control the flow of electricity.
The world needs semiconductors because they are essential for many of the technologies that we rely on today. Without semiconductors, our world would be a much less technologically advanced place.
Why the world needs semiconductors?
- Semiconductors are used in almost all electronic devices. This includes smartphones, laptops, automobiles, medical gadgets, and many more items.
- Semiconductors are essential for the development of new technologies. Semiconductors, for example, are used in the development of artificial intelligence, self-driving cars, and 5G networks.
- Semiconductors are a major driver of economic growth. The semiconductor business is a trillion-dollar sector that employs millions of people worldwide.
