- Q:Hydrogen passivation mechanism of hydrogen fluoride HF in silicon wafer RCA cleaning process
- Wire cut damage layer thickness of 10 microns.Generally use 20% alkali solution in the corrosion condition at 90 C
- Q:What are the raw materials of silicon wafers
- As a variable current switch, the transistor can control the output current based on the input voltage. Different from the common mechanical switch (such as Relay, switch), the transistor uses the electrical signal to control the opening and closing, and the switching speed can be very fast, the switching speed of the laboratory can reach more than 100GHz.
- Q:Why silicon wafers are made in watts!
- Crystalline silicon photovoltaic cells have two types of monocrystalline silicon and polycrystalline silicon, with P (or n) silicon substrate, through the formation of phosphorus (or boron) diffusion Pn formation, production technology is mature, is the leading product in the photovoltaic market. The buried layer electrode, surface passivation, enhanced light trapping, dense grid technology, optimization of back electrode and contact electrode technology, improve the collection efficiency of carrier materials, optimization of anti elbow membrane, concave convex surface, high reflective back electrode, the photoelectric conversion efficiency is greatly improved. Silicon photocell area is limited, the larger the phi 10 to 20cm wafer, the annual production capacity of 46MW/a. At present, the main task is to continue to expand the scale of the industry, the development of ribbon silicon photovoltaic technology, improve material utilization. Internationally recognized as the highest efficiency under AM1.5 conditions of 24%, the space with high quality efficiency in the AMO condition is about 13.5 - 18% of the ground with a large number of production in the AM1 conditions in the more than 11 - 18%. It can reduce the cost, but the efficiency is lower, which is made by the method of directional solidification. Optimization of the silver electrode and aluminum paste screen printing, grinding and polishing process, do everything possible to further reduce costs, improve efficiency, the maximum conversion efficiency of polycrystalline silicon photovoltaic cells up to 18.6%.
- Q:What is the cutting fluid for solar wafer cutting?
- MB, HCT, NTC and other machines, the requirements of silicon cutting fluid and the proportion of silicon carbide powder is generally controlled at 1:0.92-0.95, mortar density in 1.630-1.635 can be cut quite ideal. Even if there is a greater proportion of proportion, and even mortar density of 1.67 or so will not have any problems, as long as the mortar viscosity control in 200--250 can be. But Ernst machine for mortar density is not higher than 1.57, that is to say 1.55-1.57. can control the viscosity of mortar at around 150, so the domestic silicon cutting fluid will appear in the 1.57 density with mortar, mortar viscosity may be less than 120, and if the mortar viscosity density to 150, more than 1.57, even more than 1.60. The viscosity of mortar is too large, directly will cause the machine alarm, actually influence deeper and may cause the film does not wash clean, burn, or heating of the motor, bearing on the machine itself is very wear.Therefore, the current domestic solar silicon cutting fluid, it is not very suitable for the Ernst & Young machine. The good news is that domestic users have found the defects of the machine, the machine began to replace the mortar pump from the original 0.75KW into 1.5KW, which may solve this problem.
- Q:How much is the thickness of the silicon wafer
- For integrated circuits: generally 4 inch wafer thickness of 0.520mm, the thickness of the 6 inch wafer
- Q:What is the thickness of the semiconductor wafer used today?
- We do DIP package, 4 inch wafer to be thin to 0.300mm; 6 inch wafer to be reduced to about 0.320mm, error 0.020mm.
- Q:What to do with silicon. What is the relationship between the semiconductor and the PCB board
- But a good silicon chip is not available. Because the bare silicon wafer is not easy to damage and difficult to connect. This is a process of binding, the so-called binding is bound to use a very fine gold wire from the silicon chip lead wire, received on the metal pipe, and then use the non-conductive plastic to bind the chip sealed. We generally see transistors, chips, etc. are packaged, you simply can not see the inside of the core. Of course is also useful in metal or ceramic chip shell, such as the two or three level of some high power tubes, military grade components etc., but because the metal and ceramic package cost is relatively high, so most of the circuit or engineering plastic package.PCB is a printed circuit board, is what we call the board. The copper wire and the welding of various components and chips. The manufacturing of printed circuit board, you should check the information bar, then I talk today what also don't want to do
- Q:The benefits of silicon chip
- (2) performance index of silicon steel sheetA, low iron loss. The quality of the most important indicators, countries in the world to divide the value of iron, iron loss is lower, the higher the brand, the quality is high.B, high magnetic induction. Under the same magnetic field, the silicon steel sheet with high magnetic sensitivity can be obtained, and the volume and the weight of the motor or transformer core made by it are relatively small. C, stacked high coefficient. The surface of silicon steel sheet is smooth, smooth and uniform in thickness.D, good punching. This is more important for the manufacture of small, micro motor cores.E, the surface of the insulation film adhesion and good welding.F, magnetic agingG, silicon steel sheet after annealing and pickling.
- 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 integrated circuit electronic devices should be integrated on silicon
- First of all, the general circuit of the insulator, just a carrier, it plays the role of support and insulation. As for the integrated circuit, the bottom layer is called the substrate (generally P type semiconductor), is to participate in the work of integrated circuits. CMOS process, so the Nmos substrate are connected together, are the same substrate.
