  Semiconductor - Wikipedia, the free encyclopedia
A semiconductor is a material with an electrical conductivity that is intermediate between that of an insulator and a conductor.
A semiconductor has a band gap which is small enough such that its conduction band is appreciably thermally populated with electrons at room temperature, whilst an insulator has a band gap which is too wide for there to be appreciable thermal electrons in its conduction band at room temperature.
The ease with which electrons in a semiconductor can be excited from the valence band to the conduction band depends on the band gap between the bands, and it is the size of this energy bandgap that serves as an arbitrary dividing line between semiconductors and insulators.

 Semiconductor fabrication - Wikipedia, the free encyclopedia
Semiconductor device fabrication is the process used to create chips, the integrated circuits that are present in everyday electrical and electronic devices.
The workers in a semiconductor fabrication facility are required to wear cleanroom suits to protect the devices from human contamination.
In an effort to increase profits, semiconductor device manufacture spread from Texas and California in the 1960s to the rest of the world, such as Ireland, Israel, Japan, Taiwan, Korea, Singapore and China, and is a global business today.

 semiconductor. The Columbia Encyclopedia, Sixth Edition. 2001-05
In a semiconductor there is a limited movement of electrons, depending upon the crystal structure of the material used.
Thus there are two types of semiconductor: the N-type (negative), in which the current carriers (electrons) are negative, and the P-type (positive), in which the positively charged holes move and carry the current.
Semiconductors are used to produce such electronic devices as diodes, transistors, and computer memory devices.

 Intrinsic Semiconductors
The band model of a semiconductor suggests that at ordinary temperatures there is a finite possibility that electrons can reach the conduction band and contribute to electrical conduction.
The current flow in an intrinsic semiconductor is influenced by the density of energy states which in turn influences the electron density in the conduction band.
In a p-type semiconductor, the dopant produces extra vacancies or holes, which likewise increase the conductivity.

 semiconductor - a Whatis.com definition
A semiconductor is a substance, usually a solid chemical element or compound, that can conduct electricity under some conditions but not others, making it a good medium for the control of electrical current.
An N-type semiconductor carries current mainly in the form of negatively-charged electrons, in a manner similar to the conduction of current in a wire.
In a semiconductor material, the flow of holes occurs in a direction opposite to the flow of electrons.

Today, the term "semiconductor" is used in several contexts, each with a slightly different meaning yet, ultimately, referring to the same underlying distinction.
Your standard wall switch could be called a mechanical semiconductor in that it performs as a good conductor when pushed into the UP (on) position and performs as an excellent insulator when pushed into the DOWN (off) position.
In summary then, we can conclude that a semiconductor is a monolith in its solid state (they don't work so well when you melt or vaporize them) that acts as a good electrical conductor under some conditions and as an electrical insulator otherwise.
