Q:The purpose and means of chemical etching of silicon wafers?
After slicing and grinding, the surface of silicon wafer has a layer of damage and pollution due to processing stress
Q:Why the resistivity of silicon wafer is high and low
For example, after heating resistance and cooling, more or less there will be changes in the normal temperature change, is allowed error.
Q:One hundred watts of solar panels to how many pieces of silicon wafers, 156 of single crystals and polycrystalline
Whereas it is high. If we do not consider the area, the same power, the electricity generated is the same, with high conversion rate and low exchange rate independent of all aspects of life, of course, there will be some impact. So I do not know clearly? I is a professional manufacturer of solar photovoltaic, do not understand what I can find. If you can.
Q:What are the aspects of silicon wafer testing?
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 a silicon wafer for unidirectional and bidirectional cutting? What is the difference between the two?
Bidirectional cutting line cutting, (1) from the line wheel line network and enter the waste wire wheel (2) after a certain length reverse line wheel released by the waste reverse into the line network into the line wheel (3) repeat from the line wheel into the wire and into the process of waste wire wheelBut the length of 1 is greater than 2
Q:How to make monocrystalline silicon solar cells
Phosphate glassThe process is used for solar cell production in the manufacturing process, through chemical etching silicon that is immersed in hydrofluoric acid solution, complexes six fluorosilicic acid to produce chemical reaction to produce soluble phosphorus silicon glass layer, a diffusion system to remove the node after the formation of the surface of the silicon wafer. In the diffusion process, POCL3 reacts with O2 to form P2O5 on the surface of silicon wafer. P2O5 reacted with Si to produce SiO2 and phosphorus atoms, which form a layer of phosphorus containing SiO2 on the surface of the silicon wafer. Removing phosphorosilicate glass equipment is generally composed of a main body, a cleaning tank, manipulator, servo drive system, electric control system and the automatic mixing acid system components, the main power source of hydrofluoric acid, nitrogen, compressed air, water, wastewater and exhaust heat. Hydrofluoric acid is capable of dissolving silicon dioxide because of the reaction of hydrofluoric acid and silica to produce volatile four fluorinated silicon gas. If the hydrofluoric acid is too heavy, the reaction of four fluorinated silicon will further react with hydrofluoric acid to produce soluble complex and the material of the six fluorine acid.
Q:What is the price of monocrystalline silicon
The content of silicon in the earth's crust is 25.8%, which provides an inexhaustible source for the production of monocrystalline silicon. Because silicon is one of the most abundant elements in the earth, the solar battery that destined to enter the mass market (mass market) products, reserves of advantage is to become one of the reasons the main photovoltaic silicon materials.
Q:Why is it not easy to use high resistance on the silicon chip integrated circuit
In some places, the resistance of the epitaxial layer is adopted, and the resistance is N type, which has a lot of inconvenience in the circuit, and the numerical value is also very difficult to do
Q:What is the meaning of a cleaning in a semiconductor silicon wafer process? RCA?
() SPM:H2SO4 /H2O2 120 to 150 DEG C SPM has a high oxidation capacity, can be dissolved in the metal oxidation solution, and the oxidation of organic matter to generate CO 2 and H2O. The use of SPM to clean silicon wafers can remove heavy organic contaminants and some metals on the surface of silicon wafer, but it is difficult to remove organic matter when organic matter is particularly serious.
Q:The meaning of various names
Need some wafer to test the state of the art production equipment, such as particle, etching rate, defect rate and so on, these are often called wafer control chip, the control plate is also used to group together with the normal production process to test the quality condition of a process, such as the CVD film thickness. Production equipment in the maintenance or repair immediately after. Production batch of wafer, easy to cause the scrap, and usually use some very low cost wafer to run the process to determine the quality of maintenance or repair work, this type of wafer is called dummy wafer, of course, sometimes dummy wafer also can be used in the normal production process, such as certain machine wafer must process to a certain number the problem with dummy wafer. And some machine must be a form of dummy run in the process of a certain number of wafer, otherwise the process can not guarantee the quality and so on and so on many of the wafer are Dummy. can be called a wafer chip can be basically regarded as a dummy.Dummy wafer, control, block and so on are usually recyclable
