Semiconductors are the foundation on which modern electronics are built. From computer chips to cell phones to LED lighting, semiconductors are ubiquitous to all electronics. The word “semiconductor” is a little bit of a misnomer, as they are neither conductors nor insulators—they are semiconductors, or materials that conduct electricity only to a certain degree under a certain amount of voltage. Semiconductor manufacturing company began in the 1950s. Semiconductor technology is used in the production of many electronic devices such as computers, mobile phones, cellular and satellite radio, DVD players, and MP3 players.

A semiconductor is a crystalline material that has electrical conductivity due to a doped (or impure) material. It has a specific conductivity type, which is related to the intrinsic properties of the material. Semiconductors are used for many applications, including solar cells, light-emitting diodes (LEDs), transistors, microprocessors, diodes, and integrated circuits.

Properties of Semiconductor

A semiconductor is a material that is neither a good conductor of electricity nor a good insulator.  This can be an intrinsic property of the material itself, or it can be a result of the process used to make the material.  In either case, the materials are then classified as semiconductors, which are the materials used in most modern day electronics. These properties of semiconductor are essential for modern day electronics because semiconductor properties allow for both amplification and switching of electrical signals.

Transistors are tiny electrical devices that can be used to amplify and switch electronic signals. They can be found in almost all modern electronics, from computers to cell phones. The manufacturing process used to create a transistor determines its electrical characteristics, which makes the semiconductor industry one of the most important sectors of the technology sector.

The semiconductor manufacturing process is the method of producing semiconductor devices (also known as integrated circuits). It is a complex process, since it involves processes such as thermal oxidation, photolithography, doping, diffusion, etching, lithography, chemical vapor deposition (CVD), metalization, packaging, and testing.

Silicon is the most widely used semiconductor material. It is a semiconductor material which turns into a conductor when it absorbs light. Silicon is found in sand and is usually used in computer chips. Silicon is about $25 per kg. Silicon is about 1.7 times heavier than air.

The semiconductor industry is a $200 billion/year industry and employs more than 2 million people. The industry is constantly looking for new materials and devices that will make computers faster and cheaper, or that will be used in new devices.
