Semiconductor
A semiconductor is a material which has an electrical resistivity and conductivity, electrical conductivity value falling between that of a electrical conductor, conductor, such as copper, and an insulator (electricity), insulator, such as glass. Its electrical resistivity and conductivity, resistivity falls as its temperature rises; metals behave in the opposite way. Its conducting properties may be altered in useful ways by introducing impurities ("doping (semiconductor), doping") into the crystal structure. When two differently doped regions exist in the same crystal, a semiconductor junction is created. The behavior of charge carriers, which include electrons, ions, and electron holes, at these junctions is the basis of diodes, transistors, and most modern electronics. Some examples of semiconductors are silicon, germanium, gallium arsenide, and elements near the so-called "metalloid staircase" on the periodic table. After silicon, gallium arsenide is the second-most common s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

MStar Semiconductors
Man-portable Surveillance and Target Acquisition Radar (MSTAR) is a lightweight all-weather battlefield Doppler radar operating in the J band. It is usually used by artillery observers to acquire and engage targets in bad visibility or at night. It is capable of detecting, recognizing and tracking helicopters, slow moving fixed-wing aircraft, tracked and wheeled vehicles and troops, as well as observing and adjusting the fall of shot. The radar display is an electro-luminescent screen that can be overlaid with a map grid. It also shows the areas of ground visible to the radar and those that are masked by terrain. Target location can be presented as either map coordinates or bearing and distance (polar coordinates) from the radar. The complete radar weighs It can detect targets out to , with a maximum range of . The radar head (antenna and electronics) are connected by remoting cable to the display.

Atom (system On Chip)
Atom is a system on a chip (SoC) platform designed for smartphones and tablet computers, launched by Intel in 2012. It is a continuation of the partnership announced by Intel and Google on September 13, 2011 to provide support for the Android operating system on Intel x86 processors. This range competes with existing SoCs developed for the smartphone and tablet market from companies such as Texas Instruments, Nvidia, Qualcomm and Samsung. Unlike these companies, which use ARM-based CPUs designed from the beginning to consume very low power, Intel has adapted the x86-based Intel Atom line of CPU developed for low power usage in netbooks, to even lower power usage. Since April 2012, several manufacturers have released Intel Atom-based tablets and phones as well as using the SoCs as a basis for other small form factor devices (e.g. mini PCs and stick PCs).
