The semiconductor materials used in electronic devices are doped under precise conditions to control the concentration and regions of p- and n-type dopants. A single semiconductor device crystal can have many p- and n-type regions; the p–n junctions between these regions are responsible for the useful electronic behavior.
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.
The term solid-state became popular at the beginning of the semiconductor era in the 1960s to distinguish this new technology. A semiconductor device works by controlling an electric current consisting of electrons or holes moving within a solid crystalline piece of semiconducting material such as silicon, while the thermionic vacuum tubes it replaced worked by controlling a current of ...
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.

MEMS became practical once they could be fabricated using modified semiconductor device fabrication technologies, normally used to make electronics. [3] These include molding and plating, wet etching ( KOH , TMAH ) and dry etching ( RIE and DRIE), electrical discharge machining (EDM), and other technologies capable of manufacturing small devices.
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.
These will be based on diamond and aluminum nitride technology, which revolutionizes semiconductor electronics by increasing power delivery and thermal management in sensors and other electronic ...
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. Its roots can be traced to the invention of the transistor by Shockley , Brattain , and Bardeen at Bell Labs in 1948.
