A semiconductor is a material that is between the conductor and insulator in ability to conduct electrical current. [1] In many cases their conducting properties may be altered in useful ways by introducing impurities (" doping ") into the crystal structure .
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).
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
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 ...
The yield point of organic semiconductors is the stress or strain level at which the material starts to deform permanently. After this point, the material loses its elasticity and undergoes permanent deformation. Yield strength is usually measured by conducting tensile testing.
Intel is planning a $20 billion semiconductor factory in Greater Columbus. But first, let's back up a bit and cover the basics of semiconductors.
The insulating material has traditionally been a form of SiO 2 or a silicate glass, but recently new low dielectric constant materials, also called low-κ dielectrics, are being used (such as silicon oxycarbide), typically providing dielectric constants around 2.7 (compared to 3.82 for SiO 2), although materials with constants as low as 2.2 are ...
In my opinion, Taiwan Semiconductor Manufacturing (NYSE: TSM) is the best-positioned name in semiconductors over the next decade. Below, I'll detail what makes TSMC such a compelling long-term ...
