Phosphide indium (INP) as a new type of semi insulating wafer, it has important significance for improving and improving the performance of InP based microelectronic devices. The semi insulating wafer prepared by high temperature annealing process can not only maintain the high resistance characteristics of the traditional native iron doped substrate, but also improve the electrical properties, uniformity and consistency. The characteristics of indium Indium Phosphate crystal. It is made of metal indium and phosphorus in the quartz tube heating reaction system. Mainly used in the production of semiconductor materials and optical fiber communication technology.
The industry chain, the first by the most upstream of the crude indium indium containing mineral or waste, will be processed into indium content higher crude indium (probably more than 98%); and then by the refined indium processing plant crude indium processing refining and processing, more than 99.995% of refined indium; and then through the chemical reaction with phosphorus made indium indium indium crystal; finally by the downstream application vendors for semiconductor materials, optical fiber communications.

Phosphide indium industry chain model

In recent years, the rapid development of China's phosphide indium Market
China's phosphide indium crystal industry development started late, due to technology and brand and other aspects of the defect, has not been widely accepted by the market to accept the independent brand. In the domestic Indium Phosphate Market, but also more developed countries of technology and products, which. Agilent and the crystal technology group is a market leader, two groups are currently in China with subsidiary or is a joint venture company.
In recent years, the rapid development of the market for the development of semiconductor materials market in phosphide indium. Semiconductor materials as belonging to the "multi flowered", is widely used in the field, mainly concentrated in integrated circuits, solar battery, high-end power device, a memory, a microprocessor, a chip, an analog circuit, discrete devices and electronic power devices, detectors, led, LD photoelectric field, power electronic devices, semiconductor lighting, solar cells, such as field.
2014 1-6 month, the output value of the single crystal rod, the chip industry reached 13061000000 yuan, an increase of 25.2%. In 2013, the output value reached 25647000000 yuan, and the output value reached yuan, an increase of 16.1%.
Ministry of industry and information technology in July 2013 promulgated the "new materials industry standardization work three year action plan". "Plan", by 2015, the completion of 200 key standards system revision work, project and start 300 new material standards, to carry out 50 key criteria for pre research, to cover the "five year" plan put forward 400 key new materials products, basic form key areas of development in urgent need, with innovative achievements and international standard system. Strive to build up a new material industry to adapt to the development of the new material industry, and have a certain forward-looking industry standard system for 3 years.
The introduction of the new material industry standardization work three year action plan is to promote the standardization of new materials industry, rare metal materials is an important part of the new material industry. Semiconductor materials, magnetic materials, high performance cemented carbide materials, lithium ion battery materials, rare earth materials, high temperature alloy materials, superconducting materials and other new materials are not rare metal materials. From a variety of new material industries involved, including tungsten, cobalt, silicon, germanium, indium, gallium, bismuth, and other rare metals.
(www.cu-market.com.cn), the Research Report on the industry analysis and market development of China's Indium indium indium (2014-2018) released by spzx-bj, shows that the rare metals such as silicon, indium, gallium, germanium, etc. are important semiconductor materials, which are widely used in the field of information technology and new energy. Silicon, monocrystalline germanium and indium phosphide, arsenic indium, gallium arsenide, gallium nitride, compound single chip is used for the integrated circuits in the field of microelectronics and Optoelectronics light-emitting diode LED, laser and so on. These semiconductor single crystals are widely used in mobile phone chip, radar, optical fiber communications, tablet PC display, LED lighting and other fields. In addition, in the new energy field, crystalline silicon solar cells, copper indium gallium tin thin film solar cells, cadmium, cadmium, cadmium, solar cells, and GaAs solar cells also can not be separated from the silicon, indium, gallium, indium and other semiconductor materials.
