Q:After cutting a few chips, mortar density is getting lower and lower
Iron powder and silica fume more and more, the density should be more and more big, unless it is your water content is higher and higher
Q:Why integrated circuits are rectangular and the silicon chips are round
Chip makers use a number of processes to integrate the integrated circuit on the circle. And an integrated circuit with more than a dozen or even hundreds of chips. After the completion of the results according to India to cut it, cut into small pieces of a small square. Then the small silicon chip is packaged with other materials and pins into an integrated circuit chip.
Q:The benefits of silicon chip
(1) classification of silicon steel sheetA and silicon steel sheet can be divided into two kinds: low silicon and high silicon. Low silicon silicon containing less than 2.8%, it has a certain mechanical strength, mainly used in the manufacture of motor, commonly known as dynamosheet; high silicon silicon content is 2.8%-4.8%, it has good magnetic properties, but more brittle, mainly used in the manufacture of transformer core, commonly known as the transformer silicon steel sheet. There is no strict limit in the actual use, the use of large silicon wafer manufacturing large motor. B, according to production and processing process can be divided into two kinds of hot rolling and cold rolling, cold rolling can be divided into grain orientation and grain orientation of the two. Cold rolled sheet of uniform thickness, good surface quality, high magnetic, therefore, with the development of industry, the trend of hot rolled sheet is cold rolled sheet has replaced (China has explicitly requested to stop the use of hot rolled silicon steel sheet, which is called "pre cold generation of heat")
Q:What are the difficulties of silicon wafer cutting?
1, the impurity line caused by impurities in polycrystalline silicon ingot, slicing process can not completely remove the lead line on a silicon wafer.2, scratch line caused by mortar in large SIC particles or caking mortar. In the process of cutting, SIC particles stuck in between steel wire and silicon can not overflow, cause.Forms: including the whole line and half line marks, concave line, shiny, more narrow than the other.
Q:The higher the resistivity of silicon wafers, the better?!!
Low resistivity is helpful to improve the opening pressure, high resistivity and help to improve the short-circuit current, the best match between the two is about 1 -3! Own understanding!
Q:How much a piece of silicon on the board
The same power, the conversion rate of the area is small, or vice versa. If you do not consider the area, the same power, the amount of electricity generated is the same, with the high conversion rate and the low rate of change, of course, there will be some impact on life expectancy. I do not know so clear? I is a professional manufacturer of solar photovoltaic, do not understand what I can find, you can.
Q:Is a wafer a silicon wafer and a wafer?
An uncut monocrystalline silicon material is a thin wafer called a wafer
Q:Light doped and heavily doped silicon wafers
Is divided into light heavy doping, which is related to the amount of doping
Q:What's the difference between a silicon wafer and a battery?
Silicon chip, is a large piece of silicon, cut into a filmSolar cell, the mainstream is the silicon wafer made of crystalline silicon solar cells, or other solar cells: thin film solar cells, amorphous silicon solar energy, solar cells and so on
Q:Why do you use a concentrated sulfuric acid and hydrogen peroxide to wash silicon?
It is very difficult to clean, there are organic residues, this cleaning method is remedial method, belong to after the remedy, the cost is slightly higher
