Solid-state electronics

From Wikipedia, the free encyclopedia

An integrated circuit (IC) on a printed circuit board. This is called a solid state circuit because all of the electrical action in the circuit occurs within solid materials.
An integrated circuit (IC) on a printed circuit board. This is called a solid state circuit because all of the electrical action in the circuit occurs within solid materials.

Solid-state electronics means semiconductor electronics: electronic equipment using semiconductor devices such as transistors, diodes and integrated circuits (ICs).[1][2][3][4][5] The term is also used for devices in which semiconductor electronics which have no moving parts replace devices with moving parts, such as the solid-state relay in which transistor switches are used in place of a moving-arm electromechanical relay, or the solid-state drive (SSD) a type of semiconductor memory used in computers to replace hard disk drives, which store data on a rotating disk.[6]

The term "solid state" became popular in the beginning of the semiconductor era in the 1960s to distinguish this new technology based on the transistor, in which the electronic action of devices occurred in a solid state, from previous electronic equipment that used vacuum tubes, in which the electronic action occurred in a gaseous state. 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 current conducted by a gas of particles, electrons or ions, moving in a vacuum within a sealed tube.

Although the first solid state electronic device was the cat's whisker detector, a crude semiconductor diode invented around 1904, solid state electronics really started with the invention of the first working transistor in 1947.[7] The first working transistor was a point-contact transistor invented by John Bardeen and Walter Houser Brattain while working under William Shockley at Bell Laboratories in 1947.[8] Before that, all electronic equipment used vacuum tubes, because vacuum tubes were the only electronic components that could amplify—an essential capability in all electronics.

The MOSFET (metal-oxide-silicon field-effect transistor), also known as the MOS transistor, was invented by Mohamed M. Atalla and Dawon Kahng at Bell Labs in 1959.[9][10][11][12] The MOS transistor's advantages include high scalability,[13] affordability,[14] low power consumption, and high density.[15] The MOS transistor revolutionized the electronics industry,[16][17] and is the most common semiconductor device in the world.[11][18]

The replacement of bulky, fragile, energy-hungry vacuum tubes by transistors in the 1960s and 1970s created a revolution not just in technology but in people's habits, making possible the first truly portable consumer electronics such as the transistor radio, cassette tape player, walkie-talkie and quartz watch, as well as the first practical computers and mobile phones.

Examples of solid state electronic devices are the microprocessor chip, LED lamp, solar cell, charge coupled device (CCD) image sensor used in cameras, and semiconductor laser.
