LED industry chain can be divided into five parts. First, the raw materials. Second, LED upstream industry, including epitaxial materials and chips. Third, LED midstream industry, including a variety of LED devices and packaging. Four, LED downstream industries, including various LED application products industry. Fifth, test equipment and production equipment.
About LED upstream, midstream and downstream industries, as detailed below will be highlighted here and test equipment and industrial raw materials production equipment industry.
LED light-emitting materials and devices, including raw materials, single crystal gallium arsenide substrate materials, such as aluminum nitride single crystal. Most of them are III-V compound semiconductor single crystal, production process is relatively mature, there are signs on the use of polished delivery. High-purity gallium metal other raw materials as well, high-purity metal-organic sources such as trimethyl gallium, triethyl gallium, trimethyl smoke, trimethyl aluminum, high-purity ammonia gas, nitrogen and hydrogen and so on. The purity of raw materials in general have more than 6N. Packaging materials are epoxy, ABS, PC, PPD, etc.
Epitaxial materials testing instruments are double-crystal x-ray diffraction, fluorescence spectroscopy, Rutherford backscattering spectrometer channel and so on. Chip, the device test instruments are LED photoelectric characteristics tester, spectrum analyzer, the main test parameters for the forward and reverse voltage, current characteristics, the normal light intensity, angular distribution of light intensity, luminous flux, peak wavelength, dominant wavelength, color cursor , color rendering index. MOCVD equipment production facilities there, liquid phase epitaxy furnace, coating machines, lithography, dicing machine, automatic solid crystal, gold wire bonder, Si-Al-wire ultrasonic pressure welding, gluing machine, a vacuum oven chip counter, chip detector, inverted membrane machine, light color electric automatic sorting machines.
