Semiconductor Systems or Components



integrated circuits, semiconductors

A Semiconductor is an element which is intermediate of conductor and an insulator. Semi-conductor is kind of material that contains electrical conductivity value between a conductor and an insulator such as copper or glass. Semi-conductors are the base of modern electronics. Semi-conductors are responsible for the computer Technology and its formation, which began in the mid of 20th century and still continuing.

Semiconductor devices or electronic circuit components made from a material that is neither a good conductor nor a good insulator (called semiconductor). These devices have found wide applications because of their reliability, compactness, and very low cost. Semi-conductor systems or components are actually electronic components that take advantage of the electronic properties of the semi-conductor materials such as germanium, silicon and gallium arsenide. With the invention of the semiconductor devices have replaced most of the most of the vacuum tube applications. A semiconductor device is manufactured as either single discrete device or as integrated circuits. The integrated circuits include a few number to few million devices interconnected to a single semiconductor substrate. The cause why the semiconductor equipments are used in developing most devices is that the behavior of a semiconductor can easily be controlled by adding impurities which is or else called as doping. Transmission in a semi conductor occurs by free electrons which on the whole are called as the charge carriers.

Semiconductors have massive impact on our society. Semiconductors mostly presents at the heart of microprocessor chips as well as transistors. Anything that's automated or uses radio waves depends on semiconductors. Today's mostly semiconductor chips and transistors are created with silicon. We may have heard words like "Silicon Valley" and the "silicon economy," and that's why -- silicon is the heart of any electronic device.

A list of Semiconductor Components and devices includes Gunn diode, Avalanche diode, Light-emitting diode, PIN diode, IMPATT diode, DIAC, Schottky diode, Diode, Laser diode, Photocell, Tunnel diode, Solar cell, VCSEL, VECSEL and Zener diode are two terminal devices. The three terminal devices includes Darlington transistor, Bipolar transistor, Field effect transistor, IGBT, GTO, (Switched Gate Commuted Thyristor),SCR (Silicon Controlled Rectifier), SGCT, Thyristor, TRIAC, Unijunction transistor. The four terminal devices contains Hall Effect sensor (magnetic field sensor), Microprocessor, Multi-terminal devices comprises of Charge-coupled device (CCD), Read-only memory (ROM), Random Access Memory (RAM), and the list goes on.
