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:Why silicon wafers are made in watts!
A - (Si) amorphous silicon cells usually use high frequency glow discharge method to decompose the silane gas. Due to the low deposition temperature, the film can be deposited on glass, stainless steel plate, ceramic plate and flexible plastic sheet with a thickness of about 1 m, which is easy to large area (05rn * l.0m), and the cost is low. The structure of P in is adopted. In order to improve the efficiency and improve the stability, sometimes also made of three layers of P in multilayer laminated structure, or insert some transition layer. Its commercial production continued to grow, with an annual output capacity of 45MW / A, 10MW production line has been put into production, the global market volume of about 10 million per month, ranking first in the thin film battery. The development of integrated a - Si solar battery components, the use of the effective area of laser cutting is more than 90%, small area conversion efficiency increased to 14.6%, a large production of 8 to 10%, the highest efficiency of the laminated structure is 21%. Research and development trend is to improve the characteristics of the film, the precise design of photocell structure and control the thickness of each layer, improve the interface between the layers of state, in order to achieve high efficiency and high stability.
Q:Why integrated circuits can be etched on silicon
And for why it's cheaper to use silicon, it's not because of its semiconductor nature that it uses it. The formation of P and N, a multi hole, a multi electron, and thus the role of different doping. GaAs expensive, but the performance is good, mostly for high-speed circuits and military aspects.
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:What is a silicon wafer for unidirectional and bidirectional cutting? What is the difference between the two?
The cutting line is cut in one direction, and the wire is cut into the waste wire wheel from the discharge wheel
Q:What is the silicon area of the 125 diagonal of a single crystal of 160?
160 refers to the diagonal length of the chamfer, you draw a map can be calculated, the specific algorithm is:
Q:After cutting a few chips, mortar density is getting lower and lower
PEG water absorption is very strong, as long as the air humidity is slightly higher, then did not cut the water content of a mortar on the rise, as well as the viscosity of mortar and mortar temperature is related to the temperature difference, the viscosity of mortar to a difference of about 10
Q:Monocrystalline silicon processing technology
Cut diameterFine cutting lines mean lower kerf loss, that is to say with a piece of silicon can produce more silicon. However, the cutting line is thinner and more prone to fracture.loadThe total area of each cut is equal to the area of the wafer X the number of silicon blocks per cut X the number of chips per silicon block.Cutting speedThe cutting table cuts the speed of the web through the cutting line, which is largely determined by the cutting line moving speed, the motor power and the cutting wire tension.Easy maintenanceNeed to replace the wire cutting line and grinding slurry in cutting, maintain faster, higher overall productivity.Producers must balance these factors to maximize productivity. Higher cutting speed and greater load will increase the tension of the cutting line and increase the risk of breakage. Since all the chips on the same silicon chip are cut at the same time, as long as there is a cutting line broken, all the chips have to be discarded. However, it is not advisable to use a thicker and stronger cutting line, which reduces the number of wafers produced per cut and increases the consumption of silicon materials.
Q:Silicon wafer cleaning after the two sides of the upper and lower grille also has a basket of flowers (Bai Yin)
You don't think about it, because it's not a simple process parameter, what is the material, is a comprehensive problem of Chemical Physics
Q:How many watts can a piece of silicon produce
A piece of silicon, has been able to integrate 160 thousand transistors. What a fine project! This is the crystallization of multidisciplinary collaborative efforts, is another milestone in the progress of science and technology.
