Q:What is the thickness of the semiconductor wafer used today?
0.670mm or so. The wafer must be thinned, otherwise the loss of the dicing knife is very large, and it is necessary to draw two knives
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:What is the meaning of the wafer (100), the crystal orientation index or the crystal plane index
The coordinate system is set up in the crystal cellIs the coordinate of the direction vector
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: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 difference between silicon wafer P111 and P100
<111> is the coordinate of the direction vector<111> is expressed over the origin and point x = 1, y = 1, Z =1 on a straight line passing through the atom
Q:What is the cutting fluid for solar wafer cutting?
Because in the China multi wire cutting machine was first used in semiconductor cutting, so that only the Swiss MB and HCT, the Swiss system thinking line cutting machine with special emphasis on power and environmental protection, so that this kind of machine in the cutting process of mortar viscosity requirement is relatively high, the most direct embodiment is to use the cutting fluid is oily, reflected in the raw material cutting fluid is used to peg, otherwise, the power will be the formation of excess waste machine. NTC is the rise in the solar industry on the occasion, we seize the opportunity, to imitate the Swiss line cutting machine design and production, but the Swiss precision machine modified to virtually out of order, the rapid development of the pursuit of efficiency of solar wafer cutting industry, especially to the rise of China solar wafer cutting industry thus, China quickly occupied the market leader, the share reached 65%. However, the company has done a little better, although the power system and the power of the machine to reduce a lot, you can use the machine in the use of cutting fluid on the Swiss machine standards. Oily cutting fluid cutting efficiency and surface cut out of the film is generally better than the aqueous solution of cutting fluid, but the performance of Japanese light wire cutting machine, which he used oily fluid will cause a burden on his power, so Japanese developed this kind of water-based cutting fluid. Regardless of the cost or the use of the Japanese machine are more consistent, and easy to recycle. This NTC machine oil cutting fluid and water-based cutting fluid can be used.
Q:How to make the photoresist and silicon substrate adhesion better
PR and the same solvent for the HMDS can be better combination, adhesion will be better, will not produce bubble. You can search the TOK OAP material. That's what it's supposed to be
Q:What is the specific way to clean the silicon wafer suede concrete steps
LED epitaxial wafer process:Over the past decade, in order to develop high brightness blue light-emitting diode, all over the world, the relevant research personnel are fully invested. The commercialization of products such as blue and green light-emitting diode two LED and laser diode LD application of the - III - V elements of the potential. In the current commercial LED materials and technology extension, red and green light emitting diodes are mainly epitaxy growth method of liquid phase epitaxy, and yellow, orange light emitting diode is still in vapor phase epitaxial growth method to grow P GaAs GaAsP materials.In general, the growth of GaN requires a very high temperature to interrupt the NH3 of the N-H solution, on the other hand, the kinetic simulation also learned that NH3 and MO Gas will react to produce no volatile by-products.
Q:What is a silicon wafer
Silicon is an important material in the IC fabrication, through photolithography and ion implantation on the silicon wafer and other means, can be made into various semiconductor devices made of silicon chip. With amazing computational capabilities. The development of science and technology promotes the development of semiconductor. Development of automation and computer technology, this makes the silicon chip (integrated circuit) high technology product cost has been reduced to a very low degree. This makes the silicon wafer has been widely used in aerospace, industry, agriculture and national defense, and even crept into every family.
