What is Semiconductor Technology, and How Does it Work?

While we won’t get super into the nitty gritty here, a semiconductor is any material that has an electrical conductivity between a conductor (such as copper) and an insulator (such as rubber or glass). The conductivity of a semiconductor by introducing impurities or defects into the crystal structure of the material.

The most used is silicon, which is widely used in producing integrated circuits (ICs), also known as microchips. These chips contain multiple transistors, which act as switches that allow the flow of electricity to be controlled, enabling complex electronic functions.

Other common semiconductor materials include germanium, gallium arsenide, and indium phosphide. These materials have unique properties that make them suitable for specific applications, such as high-speed communication systems or solar cells.

There are of semiconductors:

• An N-type semiconductor is when there is a large number of free electrons or when its conductance is higher
• A P-type semiconductor is when there are less free electrons and when its inductance is lower.
  
  

Examples of Semiconductor Technology

Semiconductors have different applications — each with a different purpose or advantage.

• Diodes allow current to flow in only one direction, commonly used in power supplies and lighting applications.
• Transistors act as switches or amplifiers and are a fundamental building block of digital electronics.
• Microprocessors are ICs that contain a CPU, memory, and other circuitry and are the brain of many electronic devices such as computers, smartphones, and home appliances.
• Solar cells convert sunlight into electricity and are made of semiconductor materials like silicon.
• LED lights are semiconductor devices that emit light when a current is applied and are used in lighting applications.
