Q:The metal in the silicon wafer
By 1960, the scale of industrial production had been in this way. Silicon rectifier and thyristor has prompted the silicon material production jumped in the first semiconductor material. With the development of silicon epitaxial single crystal technology and silicon planar technology in 60s, it not only makes silicon transistor manufacturing technology mature, but also promotes the rapid development of integrated circuits. In early 80s the world's polysilicon production reached 2500 tons. Silicon is one of the promising materials for solar cells. The technology of producing solar cells with polycrystalline silicon has been mature; amorphous silicon films have been developed rapidly. Chemical element silicon. Electrically active impurities phosphorus and boron should be less than 0.4ppb and 0.1ppb in qualified semiconductor and polysilicon. A certain amount of electroactive impurities should be added to the single crystal to obtain the required conductivity and resistivity. Heavy metals such as copper, gold, iron and nonmetal are very harmful impurities. The carbon content in silicon is higher than that of 1ppm. When the carbon content is over 3ppm, the harmful effect is more significant. Oxygen content in silicon is very high. Oxygen is both beneficial and harmful. The content of oxygen in Czochralski silicon is within the range of 5 to 40ppm, and the oxygen content of the fused silica can be less than 1ppm.
Q:Development trend of monocrystalline silicon wafer
LDK LDK is committed to the development of a solar polysilicon materials, ingots and silicon chip R & D, production, sales as one of the world's leading PV enterprises". In the field of polysilicon, polysilicon LDK LDK project to establish a closed-loop circulation system of the most advanced production technology, and all components of waste will be recycled, not only cost savings, but also protect the environment, to solve the biggest bottleneck in polysilicon production technology. After the project is put into production, the cost control will be far beyond the current level of production in China to reach the international advanced level. This will be China's most promising in the environment, scale, cost, quality and other aspects of the overall success of the silicon material project. By 2009, LDK LDK is expected to become the world's leading production capacity of the largest, most technologically advanced, most environmentally friendly process of polysilicon and solar wafer production base. The first practical photovoltaic slicing machine was born in 1980s, it originated from the research and work of Dr. Charles Hauser. Dr. Charles Hauser is the founder of the Swiss HCT slicing system, which is now the predecessor of the application materials company PWS precision silicon wafer processing system division. These machines use a cutting line with a slurry to complete the cutting action. Today, the main structure of the silicon ingot and wafer cutting machine is still based on the original Charles Dr. Hauser machine, but the processing load and cutting speed has been significantly improved.
Q:After the velvet or the original silicon
After the wafer is not cleaned clean, you should be monocrystalline wafers
Q:Hydrogen passivation mechanism of hydrogen fluoride HF in silicon wafer RCA cleaning process
When the concentration of NaOH is higher than 20%W/V, the corrosion rate depends mainly on the temperature of the solution, but not on the actual concentration of the alkali solution.Removal of surface oxide layer on silicon wafer by HF:
Q:How to avoid or reduce the fragmentation of thin silicon wafers without wax polishing?
The wax free polishing template can ensure the free rotation of the silicon wafer in the groove of the template,

Q:Light doped and heavily doped silicon wafers
Otherwise, the light is mixed, N++/P++ said heavy doping, no plus is light, thank you
Q:What is a semiconductor silicon device tester
With cheap raw silicon semiconductor properties by doping using form of P type N type hole electric properties for the high-speed circuit GaAs expensive military plane
Q:Geometric parameters and testing of silicon wafer
Silicon chips have side length 125mm, 156mm, and 125 of the large chamfer diagonal 156mm and small chamfer diagonal 165mm, polycrystalline silicon chip to the side of the 156mm based, diagonal 219.2mm.
Q:What is the silicon wafer, the specific definition of what?
The chips made of silicon chips are amazingly powerful. The development of science and technology is driving the development of semiconductors. With the development of automation and computer technology, the cost of this kind of high technology product of silicon chip (integrated circuit) has been reduced to a very low level.
