Q:What is the difference between the purpose of wafer cleaning and the cleaning of silicon material, what is the difference between the acid used
A technique used to reduce the reflectivity of silicon, which is cleaned only by hydrofluoric acid
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:One hundred watts of solar panels to how many pieces of silicon wafers, 156 of single crystals and polycrystalline
This is not with the number of pieces, crystal silicon solar cell has a feature that is a 0.48-0.6V, called 0.5V, how much you want to V, you can use serial or parallel connection to achieve
Q:Consult the difference between silicon and battery
Silicon wafer is generally refers to the silicon ingot with diamond wire or just cut into pieces,
Q:What are some of the silicon wafer factory
The following is a silicon production company series positions distribution table, you can refer to the 1 equipment management department manager deputy manager of electrical equipment equipment maintenance engineer mechanical equipment maintenance Engineer Association and insurance technician equipment management maintenance team leader electric operation monitor operation duty electrician maintenance electrician maintenance mechanic subtotal
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:How to extract silicon from silicon wafers
Chamfer: the annealed silicon wafer is trimmed into an arc shape, which can prevent the wafer edge from cracking and lattice defect, and increase the flatness of the epitaxial layer and the photoresist layer. In this process, the silica fume is produced by water leaching to produce waste water and silicon slag. [1]
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:Silicon wafer cleaning after the two sides of the upper and lower grille also has a basket of flowers (Bai Yin)
I used to solve this problem for several months before the DOE experiment to solve, so it is very difficult, and there is no relationship with the bubble, and now the cleaning process does not need to bubble
Q:The problem of integrated circuit fabrication is how to realize the functions of capacitors, resistors and transistors on a single chip
You connect the line in two holes on the silicon conductive layer in the middle, this is not a resistance capacitance resistance that integrated circuit in the senior middle school physics is not the kind of silicon wafer by resistance capacitance has made but I hope you can understand the function of course this is just the front-end integrated circuit
