Silicon carbide (SiC), also known as carborundum (/ ˌ k ɑːr b ə ˈ r ʌ n d əm /), is a hard chemical compound containing silicon and carbon. A wide bandgap semiconductor , it occurs in nature as the extremely rare mineral moissanite , but has been mass-produced as a powder and crystal since 1893 for use as an abrasive .
Semiconductor device. 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 ...
Binary compounds, particularly between elements in groups 13 and 15, such as gallium arsenide, groups 12 and 16, groups 14 and 16, and between different group-14 elements, e.g. silicon carbide. Certain ternary compounds, oxides, and alloys. Organic semiconductors, made of organic compounds.
The model was first published in 1965 by Bruce Deal and Andrew Grove of Fairchild Semiconductor, [1] building on Mohamed M. Atalla 's work on silicon surface passivation by thermal oxidation at Bell Labs in the late 1950s. [2] This served as a step in the development of CMOS devices and the fabrication of integrated circuits.
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).
There are several manufacturing approaches to making silicon carbide fibers. [5] [6] The one with the longest historical experience, invented in 1975 and called the Yajima process, [7] uses a pre-ceramic liquid polymer that is injected through a spinneret to produce solidified green (unfired) fibers that go through a series of processing steps, including significant time in high temperature ...
Modern varistor schematic symbol, which is the same as a thermistor symbol [ 1 ] A varistor (a.k.a. voltage-dependent resistor (VDR)) is a surge protecting electronic component with an electrical resistance that varies with the applied voltage. [ 2 ] It has a nonlinear, non- ohmic current–voltage characteristic that is similar to that of a diode.
Bottom right: completed solar wafers. In electronics, a wafer (also called a slice or substrate) [ 1 ] is a thin slice of semiconductor, such as a crystalline silicon (c-Si, silicium), used for the fabrication of integrated circuits and, in photovoltaics, to manufacture solar cells. The wafer serves as the substrate for microelectronic devices ...
