Hong Chen, Chinese Academy of Sciences and his research team used lattice relaxation (latticerelaxation) features, to control the GaN / indium gallium nitride (GaN / InGaN) quantum well indium precipitation (precipitation), can make nitrogen Gallium Indium (InGaN) chip, the light emitted from green to white, to produce white light LED. Component in the Academy of Sciences, the emission wavelength of quantum wells is about 440nm, quantum dots are given a longer wavelength of 545 nm or light. Additional indium deposition can increase the size and density of quantum dots, in addition to the original quantum dot light emitting peak wavelength longer, the Department will also have another in the 495nm peak. The team in the GaN / InGaN quantum wells by adding a layer at the bottom of InGaN, the carrier was originally used to collect to impro...

About SMIC Semiconductor Manufacturing International Corporation (SMIC, referred to as: SMIC) Shanghai headquarters of the reception area, is hard not to feel depressed. Peeling paint on the ceiling, and the empty hall, the dim light, giving a sense of failure - and the companys balance sheet, same story. Insurmountable difficulties SMIC is Chinas largest chip maker, is not the only one encountered difficulties of the enterprise. Chinas domestic semiconductor industry was set up in the past 10 years, Chinas chip makers are still very difficult to compete with established multinational companies, and even harder to achieve profitability. Today, the global economic crisis aggravated their suffering. Recently, SMIC announced that its 2008 fourth quarter net loss doubled from a year ago to $ 124,500,000, compared with sales down 31% over...

What is the CB system concept IECEE CB system is the mutual recognition of electrical product safety test report of the first truly international system. Each countrys national accreditation body (NCB) multilateral agreements between the manufacturers can rely on a CB test certificate issued by NCB CB system, other members get national certification. CB system based on the international IEC standards. If some members of the national standards and IEC standards can not be completely consistent, but also allows the existence of national differences, but should other members of the public. CB by CB test certificate system to confirm product samples have successfully passed the appropriate tests, and in accordance with the relevant IEC requirements and requirements of the Member State concerned. CB system, the main objective is to promote int...

CCD, Charge Coupled Device that is the English abbreviation for Charge Coupled Device, which is a special semiconductor devices, with lots of the same sensor, each sensor is called a pixel. CCD by a number of sensitive units, usually in units of megapixels. When the CCD surface by light irradiation, each light-sensitive charge will be reflected in the component unit, all the signals produced by light-sensitive units together to form a complete picture. CCD uses a high-speed semiconductor material, can light into electric charge, through the ADC chip into a digital signal, digital signal compressed by the camera after the internal flash memory or internal hard disk card saved which can easily transfer the data to the computer and computer-based processing tools, and imagination needed to modify the image. CMOS, Complementary Metal Oxide ...
