The first practical application of semiconductors in electronics was the 1904 development of the cat's-whisker detector, a primitive semiconductor diode used in early radio receivers. Developments in quantum physics led in turn to the invention of the transistor in 1947 [ 7 ] and the integrated circuit in 1958.
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.
A compound semiconductor is a semiconductor compound composed of chemical elements of at least two different species. These semiconductors form for example in periodic table groups 13–15 (old groups III–V), for example of elements from the Boron group (old group III, boron, aluminium, gallium, indium) and from group 15 (old group V, nitrogen, phosphorus, arsenic, antimony, bismuth).
Max Dieckmann and Gustav Glage use the Braun tube for playback of 20-line black-and-white images. The first jukebox with records comes on the market. American Brigadier General Henry Harrison Chase Dunwoody files for a patent for a carborundum steel detector for use in a crystal radio, an improved version of the Cat's-whisker detector.
Semiconductor fabrication techniques continued to improve throughout. The Micralign, which had "created the modern IC industry", was obsolete by the early 1980s. They were replaced by the new steppers, which used high magnifications and extremely powerful light sources to allow a large mask to be copied onto the wafer at ever-smaller sizes ...
The electric power industry began in the 19th century, which led to the development of inventions such as gramaphones, radio transmitters and receivers, and television.The vacuum tube was used for early electronic devices, before later being largely supplanted by semiconductor components as the fundamental technology of the industry.
Silicon, the basic material used to build chips, is famously created in furnaces from sand or quartz by burning a mixture of coal and wood chips. Energy and water needs for the industry to ...
Apple A12 and Huawei Kirin 980 mobile processors, both released in 2018, use 7 nm chips manufactured by TSMC. [ 127 ] AMD began using TSMC 7 nm starting with the Vega 20 GPU in November 2018, [ 128 ] with Zen 2-based CPUs and APUs from July 2019, [ 129 ] and for both PlayStation 5 [ 130 ] and Xbox Series X/S [ 131 ] consoles' APUs, released ...
