Semiconductor Devices using semiconductors were at first constructed based on empirical knowledge, before semiconductor theory provided a guide to construction of more capable and reliable devices.
Extrinsic semiconductor Other devices implementing the extrinsic semiconductor:
Semiconductor device Semiconductor devices are manufactured both as single discrete devices and as "integrated circuits" (ICs), which consist of a number—from a few (as low as two) to billions—of devices manufactured and interconnected on a single semiconductor substrate, or wafer.
Reliability (semiconductor) Reliability of semiconductor devices can be summarized as follows:
Semiconductor device Semiconductor devices are electronic components that exploit the electronic properties of semiconductor materials, principally silicon, germanium, and gallium arsenide, as well as organic semiconductors. Semiconductor devices have replaced thermionic devices (vacuum tubes) in most applications. They use electronic conduction in the solid state as opposed to the gaseous state or thermionic emission in a high vacuum.
Analog Devices In 2011, Analog Devices was the third ranked analog semiconductor supplier.
Reliability (semiconductor) Failure mechanisms of electronic semiconductor devices fall in the following categories
Semiconductor package Early semiconductor devices were often inserted in sockets, like vacuum tubes. As devices improved, eventually sockets proved unnecessary for reliability, and devices were directly soldered to printed circuit boards. The package must handle the high temperature gradients of soldering without putting stress on the semiconductor die or its leads.
Semiconductor device Power semiconductor devices are discrete devices or integrated circuits intended for high current or high voltage applications. Power integrated circuits combine IC technology with power semiconductor technology, these are sometimes referred to as "smart" power devices. Several companies specialize in manufacturing power semiconductors.
Semiconductor Semiconductor devices can display a range of useful properties such as passing current more easily in one direction than the other, showing variable resistance, and sensitivity to light or heat. Because the electrical properties of a semiconductor material can be modified by doping, or by the application of electrical fields or light, devices made from semiconductors can be used for amplification, switching, and energy conversion.
GSTI Semiconductor Index The GSTI Semiconductor Index, or Goldman Sachs Technology Index Semiconductor Index, is a proprietary stock market index. It represents the weighted average stock price of a number of semiconductor companies, including Intel, National Semiconductor, Texas Instruments, Motorola, Advanced Micro Devices, SanDisk and Analog Devices.

ON Semiconductor ON Semiconductor was founded in 1999. The company was originally a spinoff of Motorola's Semiconductor Products Sector. It continues to manufacture Motorola's discrete, standard analog and standard logic devices.
Extrinsic semiconductor Extrinsic semiconductors are components of many common electrical devices. A semiconductor diode (devices that allow current in only one direction) consists of p-type and n-type semiconductors placed in junction with one another. Currently, most semiconductor diodes use doped silicon or germanium.
Semiconductor The modern understanding of the properties of a semiconductor relies on quantum physics to explain the movement of charge carriers in a crystal lattice. Doping greatly increases the number of charge carriers within the crystal. When a doped semiconductor contains mostly free holes it is called "p-type", and when it contains mostly free electrons it is known as "n-type". The semiconductor materials used in electronic devices are doped under precise conditions to control the concentration and regions of p- and n-type dopants. A single semiconductor crystal can have many p- and n-type regions; the p–n junctions between these regions are responsible for the useful electronic behavior.
ON Semiconductor ON Semiconductor is a Fortune 1000 semiconductors supplier company. Products include power and signal management, logic, discrete, and custom devices for automotive, communications, computing, consumer, industrial, LED lighting, medical, military/aerospace and power applications. ON Semiconductor runs a network of manufacturing facilities, sales offices and design centers in North America, Europe, and the Asia Pacific regions. Headquartered in Phoenix, Arizona, ON Semiconductor has revenues of $3.907 billion (2016), which puts it among the worldwide top 20 semiconductor sales leaders.
Advanced Linear Devices ALD was founded in 1985 by Robert Chao, who hired engineers and scientists from semiconductor design, technology and manufacturing backgrounds. They developed many new analog semiconductor products, particularly voltage comparators MOSFETs, and energy harvesting devices.
Semiconductor package Many devices are molded out of an epoxy plastic that provides adequate protection of the semiconductor devices, and mechanical strength to support the leads and handling of the package. Some devices, intended for high-reliability or aerospace or radiation environments, use ceramic packages, with metal lids that are brazed on after assembly, or a glass frit seal. All-metal packages are often used with high power (several watts or more) devices, since they conduct heat well and allow for easy assembly to a heat sink. Often the package forms one contact for the semiconductor device. Lead materials must be chosen with a thermal coefficient of expansion to match the package material.
Extrinsic semiconductor An extrinsic semiconductor is one that has been "doped", that is, into which a doping agent has been introduced, giving it different electrical properties than the intrinsic (pure) semiconductor. This doping involves adding dopant atoms to an intrinsic semiconductor, which changes the electron and hole carrier concentrations of the semiconductor at thermal equilibrium, the temperature at which two adjacent substances exchange no heat energy. Dominant carrier concentrations in an extrinsic semiconductor classify it as either an n-type or p-type semiconductor. The electrical properties of extrinsic semiconductors make them essential components of many electronic devices.
Shockley Semiconductor Laboratory Shockley Semiconductor Laboratory, a division of Beckman Instruments, Inc., became in 1956 the first establishment, in what came to be known as Silicon Valley, to work on silicon semiconductor devices.
