- Q:What's the difference between a silicon wafer and a battery?
- Silicon wafers are cut into pieces by wire cutting!The battery pack is a silicon wafer through the surface flocking, diffusion of PN junction, and then PECVD coating
- Q:The last time you gave me the answer to the silicon chip, I learned a lot
- Mohs hardness: 9.Density: 4 (+0.10, 0.05) g/cm 3.Optical characteristics: inhomogeneous body, one axis crystal, negative light.Color: strong. Blue: blue, green and blue; green: green, yellow and green; yellow: yellow, orange, orange orange; orange; pink: pink, purple, purple, purple and pink.Refractive index: 1.762 ~ 1.770 (+0.009, 0.005).Birefringence: 0.008 ~ 0.010.Ultraviolet fluorescence: Blue: long: no Xeon, orange; HF: no to weak, orange.Pink: long: strong, weak, orange orange; short wave.Orange: No, long wave strong, orange.Yellow: long: no to, red orange, orange red to orange: weak short wave.Color: purple, long wave: no Xeon, red; HF: no to weak, red.Colorless: no to medium, red to orange.
- Q:What is the silicon area of the 125 diagonal of a single crystal of 160?
- Because monocrystalline silicon and the battery is not a quadrilateral, so the 125 refers to the length of a single crystal square
- Q:What are the aspects of silicon wafer testing?
- Wafer inspection the main test items are: side, diagonal, chamfer, thickness, TTV, line, chipping, cracks, warping, oil, resistivity, lifetime.
- Q:What is the role of the semiconductor wafer
- You can see when the glue drops to the Wafer on a drop of liquid (uniform after the high temperature treatment, evaporation of moisture, stereotypes, said to be solid
- Q:How to avoid or reduce the fragmentation of thin silicon wafers without wax polishing?
- You can use the U.S. ZeroMicron wax free polishing template to solve the problem of non wax polishing fragments
- Q:How to detect the surface finish of photovoltaic silicon wafers, what equipment?
- Physical examination of the surface roughness on the line, whether it can be cleaned with chemical or optical
- Q:Is the thickness of solar cell silicon wafer certain? Specifically how much
- In fact, the thinner the better, because it is really used to do only 20um PN junction is enough
- Q:What can be used to adjust its viscosity
- If you are slicing, don't adjust it yourself. The final formulation of the mortar with the proportion of mixing time, there is a relationship. The proportion of the appropriate density viscosity enough to find manufacturers
- Q:P type and N type monocrystalline silicon chip difference?
- The doping of phosphorus in monocrystalline silicon is N type, the more the phosphorus is, the more free electrons, the stronger the conductivity, the lower the resistivity;
