Semiconductor - Wikipedia
A semiconductor is a material that is between the conductor and insulator in ability to conduct electrical current. [1] In many cases their conducting properties may be altered in useful ways by introducing impurities (" doping ") into the crystal structure .

Semiconductor industry - Wikipedia
The semiconductor industry is the aggregate of companies engaged in the design and fabrication of semiconductors and semiconductor devices, such as transistors and integrated circuits.It's roots can be traced to the invention of the transistor by Shockley, Brattain, and Bardeen at Bell Labs in 1948. [1] [2] Bell Labs licensed the technology for $25,000, [3] and soon many companies, including ...
Semiconductor - Simple English Wikipedia, the free encyclopedia
A semiconductor is a material that in some cases will conduct electricity but not in others. [1] Good electrical conductors, like copper or silver, easily allow electricity to flow through them. [2] Materials that block the flow of electricity, like rubber or plastic, are called insulators. [2] Insulators are often used to protect people from ...
