A semiconductor is a material that is between the conductor and insulator in ... which do not require material of higher ... The product is a function of the ...
A semiconductor device is an electronic component that relies on the electronic properties of a semiconductor material (primarily silicon, germanium, and gallium arsenide, as well as organic semiconductors) for its function. Its conductivity lies between conductors and insulators. Semiconductor devices have replaced vacuum tubes in
A microscope image of an integrated circuit die used to control LCDs.The pinouts are the dark circles surrounding the integrated circuit.. An integrated circuit (IC), also known as a microchip or simply chip, is a set of electronic circuits, consisting of various electronic components (such as transistors, resistors, and capacitors) and their interconnections.

Doping of a pure silicon array. Silicon based intrinsic semiconductor becomes extrinsic when impurities such as boron and antimony are introduced.. In semiconductor production, doping is the intentional introduction of impurities into an intrinsic (undoped) semiconductor for the purpose of modulating its electrical, optical and structural properties.
A semiconductor diode's current–voltage characteristic can be tailored by selecting the semiconductor materials and the doping impurities introduced into the materials during manufacture. [8] These techniques are used to create special-purpose diodes that perform many different functions. [ 8 ]
A transistor is a semiconductor device used to amplify and switch electronic signals and electrical power. Field-effect transistors (FET) MOSFET (metal–oxide–semiconductor FET) – by far the most widely manufactured electronic component (also known as MOS transistor) [6] [7] PMOS (p-type MOS) NMOS (n-type MOS) CMOS (complementary MOS ...
More complex circuit components can be created by further combinations of p-type and n-type semiconductors; for example, the bipolar junction transistor (BJT) is a semiconductor in the form n–p–n or p–n–p. Combinations of such semiconductor devices on a single chip allow for the creation of integrated circuits.
Because polysilicon is a semiconductor, its work function can be modulated by adjusting the type and level of doping. Furthermore, because polysilicon has the same bandgap as the underlying silicon channel, it is quite straightforward to tune the work function to achieve low threshold voltages for both NMOS and PMOS devices.
